Woody, I've not had the dietes - want some now after looking around the web. Lovely. Have you collected any seed? Said to self sow readily.

Have stored caladium bulbs and think the method would also apply to dietes. Dig when the plants have begun dying back, shake off the soil, let dry on newspaper then remove foliage. Then place the rhizomes in peat, separating them. I use cardboard boxes for storage. Will be interested to hear advice from others and then your results next spring!

Rosie in Sugar Hill

Ours was in the shade in containers. We grew it for its leaves. Beautiful and long. But since it was in the shade we had no flowers and no seed. We're actually thinking of growing it the sun next year, so we also have those beautiful flowers.
