Darwin’s orchid
Angraecum sesquipedale, family Orchidaceae
The Madagascan orchid with a long nectar spur and a famous moth pollinator
Darwin’s orchid is an epiphytic orchid native to Madagascar, known for its star-shaped white flowers with an exceptionally long green nectar spur. The flower gives off a strong spicy scent at night and is famous for its link to Charles Darwin, who predicted it would be pollinated by a moth with an equally long proboscis.
- Has a nectar spur up to 43 cm long
- Native to Madagascar’s eastern lowland forests
- Pollinated by a moth with an equally long proboscis
- Strong spicy scent at night
- Famous for its link to Charles Darwin
What does Darwin’s orchid look like?
Darwin’s orchid grows up to 1 meter tall, with dark green, leathery leaves and thick, gray roots that cling tightly to tree bark. Its flowers are star-shaped, waxy, and open green before turning white, then yellowish or orange as they age. The most striking feature is the long, green nectar spur, which can reach up to 43 cm. The flowers give off a powerful, spicy fragrance at night, reminiscent of lilies, and usually appear in small groups of one to five.
Where does Darwin’s orchid come from?
This orchid is native to the lowland rainforests along Madagascar’s east coast, often found attached to trees at forest edges where light and air circulate freely. It was first collected in 1798 by Louis-Marie Aubert du Petit-Thouars and described in 1822. The plant is adapted to humid, rainy environments with no dry season, and is rarely found growing on rocks or as a semi-terrestrial. Its story became famous through Charles Darwin, who predicted the existence of a moth with a proboscis long enough to reach its nectar, a prediction confirmed decades later.
When and how Darwin’s orchid blooms
In the wild, Darwin’s orchid flowers from June to September, while cultivated plants in Europe bloom from December to January. The plant grows best in bright, humid conditions, attaching itself to trees or sometimes rocks. Its thick roots help it anchor securely and absorb moisture. The flowers open sequentially on a long inflorescence, each developing a long nectar spur filled with sugary nectar. The plant continues to grow and bloom as long as conditions remain moist and warm.
How Darwin’s orchid is used
Darwin’s orchid is mainly admired for its unique appearance and the story of its pollination. It is grown by orchid enthusiasts for its dramatic flowers and strong night scent. There is no record in the sources of it being used in ceremonies, medicine, or as an emblem. Its main significance lies in its role in the study of evolution and plant-pollinator relationships.
Kinds of Darwin’s orchid
There are two main varieties: Angraecum sesquipedale var. sesquipedale, which is widespread in Madagascar’s eastern rainforests, and var. angustifolium, which is smaller, has narrower leaves, and grows in drier, sandy habitats in the south. The latter is sometimes called A. bosseri and is found in areas now threatened by sand mining.
What Darwin’s orchid means
Darwin’s orchid is best known for its connection to Charles Darwin, who predicted that a moth with an extraordinarily long proboscis must exist to pollinate it. This was later confirmed with the discovery of the moth Xanthopan morganii praedicta in Madagascar. The orchid’s story is often cited as a classic example of coevolution and natural selection, making it a symbol in the history of science.
