Angraecums, the Shining Stars of the Orchid World
Sparkling white flowers make Angraecums look like shining stars. This fascinating genus is native to Madagascar, tropical Africa, and islands in the Indian Ocean. They are sometimes called Comet Orchids, because thin nectar tubes hanging from the backs of their flowers inspire thoughts of comet tails. The most famous is Darwin’s Orchid, Angraecum sesquipedale. It’s shown in the first row of photos, and also called the Star of Bethlehem Orchid. Its large, tropical blooms inspired Charles Darwin to predict that a moth with a 12 inch (30 cm) tongue lived hidden in Madagascar’s jungles. This insect species would be able to reach nectar at the bottom of the long nectar spurs, pollinating the flowers in the process. The famous scientist was ridiculed at the time, but the moth was discovered decades later, helping to confirm his ideas about evolution.
There are over 220 Angraecum species and a growing list of hybrids. Sadly, most species are highly endangered and at risk of extinction. Habitat destruction, climate change, and theft of wild plants are the greatest threats to their survival. Some types are large plants, while others are miniatures. They all have flowers with nectar spurs which are fragrant at night. In cultivation, they require regular water, high humidity, good air movement, winter dormancy, and bright light, but no full sun. Most don’t like to be repotted, so they’re usually grown on mounts. That makes these orchids best for advanced growers, or for those in the tropics who can more easily accommodate them outdoors.
It’s tough to capture the beauty of these white flowers in photos. Some Angraecums boast crystalline white blossoms. Their sparkling petals glisten like a collection of tiny gems reflecting the light. Others sport a cream or light green color. Angraecum relatives with similar traits include Jumellea, Mystacidium, and Oeoniella.
