Hi Nick;

Checking our flower records, our Lycoris longituba also did the same
as our L. x squamigera this summer. None of our established clumps
flowered, but all of those divided the year prior flowered well. I
don’t know that I’ve seen this behavior documented before.

Subject: Re: [pbs] Planting depth for Lycoris

Hi Tony,

That's fascinating! I hadn't thought of Zephyranthes buds forming and
then sitting dormant until conditions are right, but it makes perfect
sense. How else could they appear so quickly after rain? It seems
reasonable that Lycoris might do the same thing.

Only one of my four clumps of L. x squamigera bloomed this year, which
isn't too far off their usual production, but my L. longituba
bulbs--which had been very reliable--didn't have a single
inflorescence. Until I see some foliage, I will be worried that they
rotted in the wet weather. Most of my L. x squamigera originally came
from a patch that my wife's grandparents planted in Pennsylvania,
probably more than 70 years ago. I doubt if it has been thinned or
replanted since then. The house is still in the family, but we rarely
visit at the right time of year to know how well the bulbs flower. I
guess I should ask.

Hi Nick;

This brings up another puzzling lycoris issue. Everything I’ve ever
read has repeated that Lycoris x squamigera flowers only after a very
cold, long winter, which is why it flowers reliably in cold climates,
but not in warmer regions...Bill suggested that our long, cool spring
in 2020 caused the buds to break, despite the mild winter
temperatures. Others have long linked rainfall with lycoris
flowering, which is certainly the case with zephyranthes. Sounds like
a great grad student project.
