FIELD NOTES & PRACTICAL KNOWLEDGE
Cultivation, identification, habitats, and the science behind Angraecum orchids. Follow your curiosity a little further.
Conservation
Angraecum orchids are almost exclusively endemic to Madagascar, where they occupy a range of forest and rock‑outcrop habitats. Most species face habitat loss, illegal collection, and climate‑related pressures, making many of them…

Both Charles Darwin (1862) and Alfred Russel Wallace (1867) correctly predicted that the Madagascan orchid Angraecum sesquipedale would be pollinated by a hawkmoth with an exceptionally long proboscis. The moth, Xanthopan morganii praedicta, was…

Bud drop (often called bud blast) in Angraecum orchids is usually a symptom of environmental stress rather than a sign that the plant needs a drastic change in routine. Before altering watering,…

Angraecum orchids should be repotted when the bark medium breaks down or the plant outgrows its pot, typically every one to two years. The optimal window is after flowering, in early spring,…

Angraecum orchids are mainly pollinated by long‑tongued hawkmoths, but research shows that some species also use birds, crickets, or can self‑pollinate. The classic Darwin prediction about a moth with a proboscis matching…

Madagascar hosts about 142 Angraecum species, 90 % of which are endemic, occupying rain‑forest canopies, dry seasonal forests, and granite outcrops. Research spans phylogenetics, pollination ecology (the classic Darwin orchid), and urgent conservation…

Angraecum orchids need watering that mimics their native wet‑dry cycles and a potting medium that stays airy yet moisture‑retentive. The exact routine varies by species—large, intermediate growers like A. sesquipedale prefer frequent watering…
