Peg,
Don't you just love those blooms! I have quite a few of that variety here which my grandfather must have planted. In my searches over the past few years, I came across a website that said zephryanthes had a short shelf life with regards to viability. Have you ever read that?

For the past 3 years, I've been collecting seeds each Spring and starting the entire group of them in wooden ammo boxes. The depth is about right and by the time the wooden boxes fall apart, they should be ready to bloom.

BTW, mine are white. What color are yours?
