Hippeastrum calyptratum is one of my favorites. The flowers are so unusual, a beautiful jade green, and the form is very orchid-like. I have two different forms, one which is a beautiful clear green and has no scent that I can detect. The other has larger flowers with pink anthers and streaks of red on the outer petals and has a very strong scent. It is in bloom now, and as soon as I enter the greenhouse it makes its presence known. The scent is not wonderful, more like something an arum would produce, and that makes me think about its pollinator, for usually these kinds of scents are there to attract flies, but H. calyptratum is said to attract bats. H. calyptratum is from Brazil, from the Organ mountains and grows as an epiphyte on trees and rocks. I haven't found it difficult to grow and it seems to enjoy our cool and humid climate. The pictures show the plain green one above, the one with pink anthers below.
