Aerangis fastuosa is a miniature epiphytic orchid from the evergreen montane forests of northern and eastern Madagascar, where it grows on the twigs and small branches of forest trees at 910–1,700 m elevation — a cooler, mist-drenched environment that sets it apart from many tropical orchids. Each plant is tiny: a very short stem carries a fan of thick, obovate, blue-grey-green leaves rarely spanning more than 8–10 cm tip to tip, yet it produces flowers disproportionately large for its size — pure white, star-shaped blooms up to 5 cm across, each with a long curved nectar spur, appearing on short arching inflorescences of 1–6 flowers in late winter to spring. The flowers are powerfully fragrant after dark, releasing a jasmine-like scent that is characteristic of many Madagascar angraecoid orchids. In cultivation it does best mounted on cork bark or fine bark mix at cool-to-intermediate temperatures, with high humidity and strong air movement — conditions a well-ventilated closed terrarium or orchidarium can provide well.

Distribution

Propagation

Like all orchids, Aerangis fastuosa can be propagated from seed, but orchid seeds lack endosperm and require symbiotic mycorrhizal fungi — or sterile laboratory flasking with a nutrient agar medium — to germinate. Flask-raised seedlings take several years to reach flowering size. This is strictly a specialist technique; division of established plants is not generally possible given the monopodial growth habit and the small plant size.
