[5][6][7][8] Angraecums are quite varied vegetatively and florally, and are adapted to dry tropical woodland habitat and have quite fleshy leaves as a consequence.
The specific name sesquipedale means "one foot and a half", referring to the length of the spur.
Many of the species, such as Angraecum sororium, are endemic to Madagascar and are threatened from over collecting, loss of hawkmoth pollinators, habitat fragmentation, and fire.
[17][5] Like all other orchids it is best to water in the mornings to avoid fungal rot due to overnight dampness.
Feeding as per other orchids and similar light conditions: in humid and hot regions (sub tropical) feed fortnightly during growing season (Summer) with a certified orchid fertiliser following directions on packet, weaker solutions are also okay if you're worried.
Most Angraecums will have their leaves for a number of years so any sun burn spots are ugly for a significant period and also may expose your plant to disease.
In indirect light and watered/fed regularly this plant will produce blooms annually (usually in late Winter to Spring - for Australia this occurs in August).
Flowers are large (4–9 centimetres (1.6–3.5 in) across), waxy, white to greenish cream in colour and borne on stems of seven to ten depending on the faithfulness of your fertilising, watering, and indirect light provision.
When watering a good soaking with a hose or watering-can is best (not just a misting from a spray gun) as this helps to flush away any salts from fertilisers that may be present in the potting mixture and also thoroughly wets the plant.
