Research Question on Zephyranthes grandiflora

1. Is there a period after transplanting during which flowering does
not occur? How long do we wait?
2. Is flowering sensitive to the daylength?
3. and the big question: Does anyone have clues into the nature of the
flowering? There is not much scientific literature out there and the
two main sources are a little dated and conflict.

Martin,

I seem to recall that someone here in Australia keeps their
rainlilies dry for 6 weeks then soaks the pot in water overnight,
triggering flowering within the next few days. The keep this cycle
going throughout the summer months, getting heaps of flowers every 6
weeks. I've never tried this myself, but apparently it worked for
him. Now if I could just remember who it was so I could put you in
touch with them. <sigh>

Cheers.
