Culture
I have found this genus very difficult to maintain in my greenhouse here in Indiana. They need more sun in winter than we have, and probably suffer in our hot, humid summer weather, even when kept dry.
They probably prefer growing in large pots if they are not over-watered.
Feed with a dilute soluble fertilize when the plant is in active growth. This is usually from late autumn or early winter onwards. In late spring, stop feeding. In summer, reduce watering or cease watering completely.
Not frost-hardy, so protect from freezing.
