Very interesting about Zephyranthes flavissima. There seems to be only one clone in commerce (no idea where it originated), and it is a poor performer and never sets viable seed. Do you know of any one that has grown this from seed and if there is much variability to the seedlings?

Z. grandiflora is from zone 10 in Mexico. Bulb hardiness depends on wether the pots are in a plunge bed or exposed to cold air.
