This beautiful plant is known in known in its native Brazil
as Queen of the Abyss, but it is sometimes sold as Brazilian Edelweiss as its
leaves resemble in some ways those of the (totally unrelated) alpine Edelweiss.
Living across southern Africa is a large group (150+
species) of mostly small, rosette forming succulent plants in the genus
Haworthia. Like their relatives the Aloes they are leaf succulents, storing
water over the long dry season in fleshy leaves. Currently in flower in my
conservatory is one of the smaller species, Haworthia pygmaea.
