Dragon's Blood Tree: Shape, Resin and Conservation

2 Sep 2026 in Green living · Updated 8 Oct 2026

The dragon's blood tree (Dracaena cinnabari) is an umbrella-shaped evergreen that grows wild only on Socotra, a Yemeni island in the Arabian Sea. It is named after the dark red resin that seeps from its bark. The IUCN lists it as Vulnerable, largely because grazing and drought stop young trees from replacing old ones.

What is the dragon's blood tree?

The dragon's blood tree is a long-lived member of the genus Dracaena, in the asparagus family. Unusually for a tree, it is a monocot, the plant group that includes palms and grasses. Most monocots cannot thicken their stems the way oaks do, but dragon trees have a distinctive form of secondary growth that lets the trunk widen slowly over many years.

Its native range is the Socotra archipelago, off the Horn of Africa. Plants of the World Online, the botanical database run by Kew, records it as native to Socotra only. It grows mostly on limestone plateaus and in the granite Haggeher mountains, where mist is frequent.

A species that grows naturally in only one place is called endemic, and Socotra is full of them. Long isolation from Africa and Arabia has produced a large share of plants found nowhere else, including several frankincense trees. This flora is a main reason the archipelago is a UNESCO World Heritage Site.

Why is the dragon's blood tree shaped like an umbrella?

The crown grows as a dense, upturned dome. After a shoot flowers, it typically divides into two or more new branches. Repeated over centuries, this produces a tightly packed canopy with stiff, sword-shaped leaves clustered at the branch tips. The shape is thought to suit a dry, windy island in several ways:

Fog capture. Rainfall on Socotra is low and irregular, but the highlands are often wrapped in mist. The upward-pointing leaves are believed to intercept droplets, which run down the branches towards the trunk and roots.
Shade. The dense crown shades the ground beneath it, reducing evaporation and keeping the soil moist for longer.
Wind. A compact, rounded crown may help the tree cope with the strong winds of the summer monsoon.

The cooler, damper ground under mature trees can also give seedlings a better start, provided animals do not eat them first.

Where does the red resin come from, and what is it used for?

When the bark is damaged, the tree exudes a resin that hardens into dark red droplets, often called "tears", and is generally understood to help seal the wound. On Socotra it has traditionally been collected from natural cracks or by scraping the bark, and it is sold locally under the Arabic name dam al-akhawain, often translated as "blood of the two brothers".

Traditional uses on the island include dyeing, decorating pottery, colouring lips and treating wounds and skin complaints. Socotran resin was traded across the ancient world, and "dragon's blood" later appeared in European varnishes, pigments and alchemical recipes. An old legend, retold by Roman writers, held that it was the blood of a dragon killed fighting an elephant. Traditional use does not show that the resin is safe or effective as a modern medicine.

The name is not unique to this tree. Several unrelated plants produce red resins or saps sold as "dragon's blood":

Source plant	Where it grows	What the "blood" is	Typical uses
Socotra dragon's blood tree (Dracaena cinnabari)	Socotra archipelago only	Resin that seeps from the bark and dries into droplets	Dye, pottery decoration, varnish, incense, traditional medicine
Canary Islands dragon tree (Dracaena draco)	Canary Islands, Madeira, Cape Verde and parts of Morocco	Resin from the trunk and branches	Historically a dye and varnish ingredient; widely grown as an ornamental
Rattan palms (such as Daemonorops draco)	Southeast Asia	Red resin coating the scaly fruit	Incense and dyes; a common source of commercially traded dragon's blood
Sangre de drago (Croton lechleri)	Western Amazon	Red latex tapped from the bark	Traditional wound care in parts of South America

Is the dragon's blood tree endangered?

The IUCN Red List currently assesses Dracaena cinnabari as Vulnerable, meaning it faces a high risk of extinction in the wild if current pressures continue. Its outlook depends on whether new generations can establish.

The central problem is regeneration, the natural replacement of old trees by young ones. In many stands almost every tree is mature, and young trees are rare outside places goats cannot reach, such as cliffs and steep gorges. The main pressures are:

Grazing. Free-ranging goats and other livestock eat seedlings, so few survive their first years.
A drier climate. Seedlings depend on mist and seasonal moisture to take hold; less of either makes establishment harder.
Storms. Severe cyclones, including two that struck the archipelago in 2015, are reported to have uprooted many mature trees.
Slow growth. A young tree takes many years to reach flowering size, so lost mature trees are not quickly replaced.

Because the species grows nowhere else, there is no other wild population to fall back on. Mature trees provide shade, moisture and shelter for insects, reptiles and birds, which is why the tree is often described as a keystone species of the Socotran highlands.

Why seedling protection and restoration matter

The dragon's blood tree shows that saving a species is not only about the trees already standing. A stand of old, healthy-looking trees can still be in decline if nothing replaces them. On Socotra, conservation work has focused on that gap: raising seedlings in nurseries, planting them in fenced plots and shielding young trees from livestock until they are tall enough to survive.

Several lessons carry over to forest restoration elsewhere:

Survival matters more than planting numbers. A seedling only counts if it lives through its first dry seasons, so protection and follow-up care often decide the outcome.
Native species suit the site. Trees adapted to local rainfall, soils and wind are more likely to establish.
Local people are central. Herders and nursery workers decide whether young trees are protected, so restoration works best when it also brings paid work locally.

Trees funded through Evertreen are planted with local partners and farmers in named projects, and planting follows the local season, typically one to six months after funding.

Frequently asked questions

Why is it called the dragon's blood tree?

The name comes from its dark red resin, which looks like dried blood. Ancient and medieval traders sold several red resins as "dragon's blood", and legends linked them to real dragons.

How old can a dragon's blood tree get?

Large trees are thought to be several centuries old, but exact ages are hard to measure. As a monocot, the tree does not lay down clear annual growth rings, so estimates usually rely on growth rates and the number of branching points in the crown.

Is dragon's blood the same as cinnabar?

No. Cinnabar is a red mineral, mercury sulphide, once ground to make the pigment vermilion. In the ancient world the two red substances were sometimes confused under similar names, which is where the species name cinnabari comes from. Dragon's blood is a plant resin.

Can you grow a dragon's blood tree outside Socotra?

It is grown in some botanical gardens and by specialist collectors, usually in warm, dry conditions or under glass. It grows very slowly and needs free-draining soil and frost protection, and cultivated plants do not replace wild populations.

Business Carbon Footprint: The Data You Need by Scope

A business carbon footprint is the total greenhouse gas emissions caused by a company's activities, grouped into Scope 1, 2 and 3. To calculate it you need activity data for each scope (fuel, electricity, purchases, travel, freight and waste), a matching emission factor for each item, and a clear record of the gaps you estimated. This article is a data checklist, not a calculation walkthrough. For the full method, from setting boundaries to reporting, see our step-by-step guide to calculating your business carbon footprint. Here we focus on the part that usually takes longest: finding the numbers. What data do you need for a business carbon footprint? Every line in a footprint follows one formula: activity data × emission factor = emissions. Activity data is a measured quantity, such as kilowatt-hours of electricity, litres of diesel or kilometres flown. An emission factor converts it into carbon dioxide equivalent (CO2e), a unit that expresses all greenhouse gases in terms of the warming effect of CO2. Public factor sets such as the UK Government's greenhouse gas conversion factors and the US EPA's Emission Factors Hub are widely used; note which edition you applied. The GHG Protocol Corporate Standard defines the three scopes. Scope 1 is direct emissions from sources you own or control. Scope 2 is purchased electricity, heat, steam and cooling. Scope 3 is all other indirect emissions in your value chain, upstream and downstream. Before collecting anything, set your organisational boundary (many smaller companies use operational control, covering the sites and vehicles they run) and a reporting year, ideally your financial year. Scope 1 and Scope 2: the data checklist This data usually sits with finance, facilities and fleet teams. Collect it by site and by month, so missing periods stand out. Gas and heating fuels (Scope 1): supplier invoices or meter readings. Replace estimated readings with actual ones. Company vehicles (Scope 1): fuel-card reports in litres; mileage logs with vehicle type as a fallback. Electricity for charging company cars at your sites goes in Scope 2. Refrigerants (Scope 1): kilograms topped up in air conditioning, heat pumps and cold stores, from service engineers' records. Small leaks matter because some refrigerants have a very high warming effect. Generators and process emissions (Scope 1): fuel purchase records and any process that releases gases directly. Electricity, heat, steam and cooling (Scope 2): kWh per meter from bills or your supplier's portal, for every site. The GHG Protocol's Scope 2 Guidance asks for electricity to be reported two ways. The location-based method uses the average factor of the local grid. The market-based method reflects your contracts, so you also need your supplier's fuel-mix disclosure and any certificates you hold, such as renewable energy certificates (RECs) in the US or Guarantees of Origin in Europe. These are energy certificates, not carbon offsets. Where does Scope 3 data come from? The GHG Protocol splits Scope 3 into 15 categories, and few businesses need all of them. For many companies, particularly those that buy in most of what they sell, Scope 3 is the largest part of the footprint, so screen every category before choosing which to measure in detail. Typical sources: Purchased goods, services and capital goods: the accounts payable ledger grouped by spend category, or quantities from purchase orders. Fuel- and energy-related activities: derived from your Scope 1 and 2 data (fuel extraction, grid losses). Transport and distribution: carrier reports or freight invoices with weight, distance and mode. Waste: contractor reports in tonnes, split by treatment. Business travel: travel agency reports with routes and cabin class, mileage claims and hotel nights. Commuting and home working: a short staff survey on distance, mode and office days. Use and end of life of sold products: sales volumes plus product energy use and materials. First footprints usually mix three methods. Spend-based multiplies money spent by an environmentally extended input-output (EEIO) factor, an average emission intensity per unit of spend in a sector. Activity-based uses physical quantities such as tonnes or kilometres. Supplier-specific uses your suppliers' own emissions data and is the most precise when that data is sound.

No first footprint has complete data. Fill gaps consistently and document them, so next year's figure is comparable. Missing months: extrapolate from the months you have, allowing for seasonal heating or cooling, and flag the figure as estimated. Shared offices: ask the landlord for building energy use and allocate your share by floor area or headcount. No supplier data: start spend-based, then replace the largest categories with activity or supplier data. Double counting: each cost belongs in one place; company-car fuel is Scope 1, not purchased goods. Changing factors: factor sets are updated regularly, so record the edition used. Keep a data log with the source, owner, date, unit and factor for each line, so the footprint can be audited and improved. Your first well-measured year becomes the base year for reduction targets; if you set one, the Science Based Targets initiative (SBTi) validates targets against its criteria but does not certify companies or footprints. Frequently asked questions What is the difference between Scope 1, 2 and 3 emissions? Scope 1 is direct emissions from sources you own or control, such as boilers and company vehicles. Scope 2 is indirect emissions from the electricity, heat, steam and cooling you buy. Scope 3 is every other indirect emission in your value chain, from purchased goods to the use of products you sell. Can I use spend data instead of activity data? Yes, especially for Scope 3 in a first footprint. Spend-based factors are sector averages, so they cannot reflect a lower-carbon supplier. Use them to find your largest categories, then move those to activity or supplier data over time. How accurate does a first business carbon footprint need to be? Accurate enough to show where your largest emissions are, and repeatable. Estimates are acceptable if documented and flagged. Accuracy should improve each year as metered or supplier data replaces estimates. Is reporting Scope 3 emissions mandatory? It depends on where you operate and your size. In the EU, mandatory CSRD reporting now applies to companies above both EUR 450 million turnover and 1,000 employees (Directive (EU) 2026/470), with simplified reporting standards (ESRS) from financial year 2027. Smaller firms are outside that scope, but larger customers often ask suppliers for emissions data for their own Scope 3 reporting. Does tree planting or buying carbon credits lower my reported footprint? No. Tree planting is a nature-based climate contribution with a modelled CO2 estimate, not an offset, and it does not reduce Scope 1, 2 or 3 figures. Certified carbon credits retired on public registries are a separate instrument; under the GHG Protocol they are reported separately, not deducted from any scope.

Reforestation in ESG Reporting: How to Report It Honestly

Reforestation in ESG reporting belongs in the contribution, biodiversity and community sections, not in the emissions inventory. Report the trees funded, the projects and partners, a modelled lifetime CO2 estimate clearly labelled as an estimate and the local working hours, and keep all of it separate from Scope 1, 2 and 3 totals and from any carbon credits. Many companies fund tree planting and then struggle to describe it in a sustainability report. This guide covers where reforestation fits, what to disclose and how to word it so that every statement can be checked. Where does reforestation belong in an ESG report? ESG stands for environmental, social and governance. Reforestation touches the first two: restored land and habitat on the environmental side, paid local work and community involvement on the social side. It does not belong in the greenhouse gas (GHG) inventory, which records the company's own emissions in three scopes: Scope 1 (direct emissions), Scope 2 (purchased energy) and Scope 3 (the rest of the value chain). The GHG Protocol Corporate Standard sets out how companies account for those emissions. Funding trees elsewhere does not change them, so the inventory figures stay the same with or without a planting project. The honest place for tree planting is a separate section, often called "climate contributions", "nature and biodiversity" or "community investment". The Science Based Targets initiative, which validates corporate targets, treats this kind of action as beyond value chain mitigation: welcome, but in addition to cutting emissions, not instead of it. What should a company disclose about the trees it funds? For each project, record: Trees funded and planting status. State how many trees were funded in the year and how many have been planted so far. Planting follows the local season, so trees funded late in the year may be planted in the next reporting period. Project, country and partner. Name the project and the local partner that does the planting, for example a mangrove project in Kenya or a highland forest project in Madagascar. Modelled CO2 estimate. Give the CO2 the trees are estimated to absorb over their lifetime, with the method and time frame, and label it as a modelled estimate, not measured removals. Community outcomes. Report estimated working hours or other social indicators supplied by the project, and say that they are estimates. Biodiversity context. Note the ecosystem being restored, such as mangroves, tropical forest or savannah, and any habitat protection linked to the project. Evidence. Keep certificates, photos and project updates on file. Sponsors follow their trees online through the project location, photos and updates. Evertreen labels its own figures the same way: more than 3,680,000 trees funded through Evertreen, tree planting funded in 29 countries, more than 2.9 million tonnes of CO2 estimated over the lifetime of those trees, and more than 460,000 working hours for local communities (estimated). Project details are on Evertreen's transparency page. How do tree planting, carbon credits and energy certificates differ in a report? Tree planting is often listed next to other climate actions, but each has a different purpose and place in the report. Mixing them up is a common source of misleading claims. ActivityWhat it isWhere it goes in the reportWhat you can state Funded tree plantingTrees funded by the company, planted by local partners, with a modelled lifetime CO2 estimateContribution, biodiversity and community sections, outside the GHG inventoryTrees funded and planted, projects, estimated CO2, estimated working hours Certified carbon creditsUnits from third-party projects certified under standards such as Verra or Gold Standard, retired on public registriesA separate disclosure next to the inventory, not deducted from Scope 1, 2 or 3Credits retired, project, standard, vintage, registry record RECs and Guarantees of OriginEnergy certificates for electricity: RECs in the United States, Guarantees of Origin in EuropeElectricity and Scope 2 disclosures, under the market-based methodElectricity covered and certificates cancelled; not a carbon offset Certified carbon credits are a distinct product, issued under standards such as Verra, Gold Standard, American Carbon Registry or Plan Vivo. Under the GHG Protocol they are reported separately and are not deducted from Scope 1, 2 or 3. If your company also retires credits, for example through Evertreen's verified carbon credits, give them their own section with registry details. Funded tree planting is not a credit and should never be described in credit language. How to word reforestation claims honestly Most problems come from wording rather than from the projects. A simple test: could a reader check each sentence against your records? Say "funded" until trees are in the ground. For example: "In [year] we funded [number] trees through Evertreen, planted with local partners in [country] as the planting season allows." Attach "estimated" to every CO2 figure. For example: "These trees have a modelled lifetime CO2 estimate of [number] tonnes. This is not a carbon credit and is not deducted from our reported emissions." Keep time frames visible. Young trees take years to grow, so do not present a lifetime estimate as something achieved in the reporting year. Do not net anything. Avoid phrasing that suggests the trees cancel or compensate for the emissions in your inventory. Describe your role accurately. The trees were funded by the company and planted by a local partner; they are not company assets. Linking reforestation to CSRD, GRI and the SDGs Reporting frameworks have no dedicated line for tree planting. Under the EU Corporate Sustainability Reporting Directive (CSRD), mandatory reporting now applies to companies above both EUR 450 million turnover and 1,000 employees, following Directive (EU) 2026/470, and the simplified European Sustainability Reporting Standards apply from financial year 2027 (optional for 2026). A funded planting programme usually sits outside the company's own value chain, so it is presented as voluntary information beside the climate and biodiversity disclosures, not inside their metrics. GRI reporters can include the funding as a community investment. For the UN Sustainable Development Goals, tree planting with paid local work relates most directly to SDG 13 (climate action), SDG 15 (life on land) and SDG 8 (decent work). Frequently asked questions Can tree planting reduce a company's Scope 1, 2 or 3 emissions? No. Scope 1, 2 and 3 figures describe the emissions a company and its value chain produce, and funding trees elsewhere does not change them. Tree planting is reported as a separate contribution with a modelled CO2 estimate. Is funding reforestation the same as buying carbon credits? No. Certified carbon credits are issued under standards such as Verra or Gold Standard and retired on public registries, while funded tree planting carries a modelled CO2 estimate and no credit. The two belong in separate parts of a report. Why are trees reported as funded rather than planted? Planting follows the local season, typically one to six months after funding, so trees funded near the end of a reporting year may not yet be in the ground. Reporting them as funded, and updating the planted figure later, keeps the statement accurate. Does reforestation count towards the social part of ESG? It can, when projects create paid local work or involve communities in caring for the land. Report the indicator used, such as estimated working hours, and say whether each figure is measured or estimated. What evidence should a company keep for assurance of its tree planting? Keep the certificates, project names and locations, project updates and photos, and the method behind any CO2 estimate. Companies in custom partnerships can also request the coordinates of their planting sites. To see how CO2 figures for funded trees are modelled, read how Evertreen estimates tree CO2.

Corpse Flower: One of the Weirdest Rainforest Plants

The corpse flower is the common name of Amorphophallus titanum, or titan arum, a giant plant that grows wild only in the rainforests of Sumatra, Indonesia. Its flowering structure can stand around 3 metres tall, opens for roughly a day or two after years of growth, and smells of rotting meat to attract carrion insects. Few plants draw queues at botanic gardens the way this one does. It is huge, unpredictable and briefly foul-smelling, and each of those traits has a purpose. This guide explains how it works, why it blooms so rarely, how it differs from Rafflesia, and why its future depends on the Sumatran forest. What is the corpse flower? Amorphophallus titanum belongs to the arum family (Araceae). It was brought to scientific attention by the Italian botanist Odoardo Beccari after he encountered it in western Sumatra in 1878, and you can check its accepted name and native range on Kew's Plants of the World Online. In Indonesia it is known as bunga bangkai, which translates as "corpse flower". What looks like one enormous flower is in fact an inflorescence: a cluster of many small flowers on a single structure. It has two main parts: The spadix, the tall, pale central column that rises out of the middle. The spathe, a frilled sheath wrapped around the base of the spadix, green on the outside and a deep maroon on the inside when open. The real flowers are tiny and hidden inside the spathe, in rings around the base of the spadix: female flowers below, male flowers above. Because these flowers sit on one unbranched stalk, the titan arum has the largest unbranched inflorescence of any known plant. (The talipot palm produces a larger flowering structure, but it is branched.) Why does the corpse flower smell like rotting meat? The smell is a pollination strategy. A plant that flowers rarely and briefly in dense rainforest needs to be found quickly, so the corpse flower mimics a dead animal, attracting carrion beetles and flesh flies that normally seek out carcasses to feed or lay eggs on. The scent includes sulphur-containing compounds such as dimethyl trisulfide, which is also given off by decaying flesh. Three other features strengthen the illusion: Heat. The spadix warms up during the bloom, to roughly human body temperature, which helps the smell rise and spread through the forest. Colour. The maroon inner face of the spathe resembles raw meat. Timing. The spathe usually opens in the late afternoon or evening, and the smell is typically strongest during the first night, when many carrion insects are active. Insects that crawl down into the spathe reach the female flowers first. These are receptive before the male flowers on the same plant release pollen, usually about a day later. This makes self-pollination unlikely, so the plant depends on insects bringing pollen from another titan arum blooming at about the same time, a real constraint in the wild. If pollination succeeds, the base of the spadix develops into a cluster of red-orange fruits, which birds, including hornbills, are thought to eat and disperse. How often does the corpse flower bloom? Rarely, and never on a fixed timetable. The plant grows from a corm, an underground storage organ that can become very large; corms of more than 100 kilograms have been recorded in cultivation. The corm alternates between three phases: Leaf phase: a single umbrella-like leaf, several metres tall, feeds the corm for a year or more, then dies back. Dormancy: the corm rests for a few months. Flowering phase: only when the corm has stored enough energy does it send up an inflorescence instead of a leaf. A plant grown from seed often takes seven to ten years to flower for the first time, and after that there are usually several years between blooms. The bloom itself is short: the spathe stays fully open for about 24 to 48 hours before it closes and collapses. The first recorded flowering in cultivation was at the Royal Botanic Gardens, Kew, in 1889, and blooms still make the news because gardens can only predict them a few days ahead. Titan arum vs Rafflesia: which is the real corpse flower? Both. "Corpse flower" is used for two unrelated Southeast Asian plants that both smell of decay and are both called bunga bangkai in Indonesia. The titan arum has the largest unbranched inflorescence; Rafflesia arnoldii has the largest single flower. FeatureTitan arum (Amorphophallus titanum)Rafflesia (Rafflesia arnoldii) What the "flower" isAn inflorescence of many tiny flowersA single flower SizeCan reach around 3 metres tallAround 1 metre across How it livesIndependent plant with a corm and a giant leafParasite inside Tetrastigma vines; no leaves, stems or roots of its own Where it grows wildSumatra onlySumatra and Borneo Bloom lengthAbout 1 to 2 days at its peakAbout a week PollinatorsCarrion beetles and flesh fliesCarrion flies Can it be cultivated?Yes, in many botanic gardensVery difficult; rarely grown outside its habitat Both join a long list of odd rainforest plants, like the stilt-rooted palm in our article on the walking palm. Is the corpse flower endangered? Yes. The titan arum is listed as Endangered on the IUCN Red List of Threatened Species. Its wild range is limited to Sumatra, where the main pressure is the loss and fragmentation of its forest habitat, including clearance for agriculture and plantations. A small, scattered wild population also makes cross-pollination harder. Botanic gardens help by sharing pollen and seed between institutions. Many cultivated plants are thought to descend from a limited number of wild-collected individuals, so coordinated pollination is used to keep the cultivated population genetically diverse. These ex situ (off-site) collections are a backstop, not a replacement for intact forest where the plant, its pollinators and its seed dispersers live together. It is worth being precise about where Evertreen fits. Through Evertreen, people and companies fund trees that local partners and farmers plant in named projects, including rainforest reforestation in Honduras and Brazil, and tree planting in Madagascar with the partner Tsiryparma, which also guards 8,021 hectares of eastern highland forest at Vohidahy. Planting follows the local season, so trees go into the ground in the months after funding, not instantly. Separately, Evertreen acts as an intermediary for certified carbon credits from third-party projects under standards such as Verra, Gold Standard, American Carbon Registry and Plan Vivo, retired on public registries; Evertreen does not own or operate those projects, and this is a different product from tree planting. Frequently asked questions How big is the corpse flower? A mature titan arum's inflorescence can stand around 3 metres tall, and some cultivated specimens have exceeded that. The underground corm that powers it can weigh more than 100 kilograms. Is the corpse flower the largest flower in the world? It depends on the definition. The titan arum has the largest unbranched inflorescence, a cluster of many small flowers. The largest single flower belongs to Rafflesia arnoldii, at around 1 metre across. Is the corpse flower carnivorous? No. It does not trap or digest insects. The beetles and flies it attracts are pollinators: they pick up pollen and, ideally, carry it to another blooming plant. Where can you see a corpse flower bloom? Many botanic gardens in Europe, North America and Asia grow titan arums. Because a bloom lasts only a day or two, gardens usually announce it a few days ahead online, and some stream it live.
