The bulb is listed as an evergreen in as much as it doesn't have a full dormancy period as other Hippeastrum do.
Usually the first to bloom, in our area, around August, it has 2 blooms per scape but bulbs that are 6 years and older can have 3 blooms. The face of the bloom is never fully open unlike other hippeastrums. This, to me, gives a feeling of shyness but at the same time a confident elegance.
After flowering she may loose a few leaves, but this is normal as new ones are quickly replaced.
The Butterfly Hippeastrum must only be planted in an easterly position. It can not tolerate afternoon heat in summer. If the leaves are touched by the afternoon sun they suffer a 'sun burn' effect which is very hard for the plant to recover from. It has also been said that she is an inconsistant flowerer, but I have not found this to be the case in my garden.
If the bulb receives too much water the leaves will turn yellow and drop off. Best to feed with a liquid fertiliser and allowed to dry out between waterings.
