Hi Arnold:

I have posted this before, so apologies to those who remember it.

I moved my Lycoris from the hot interior of California to the cool coast a
few years ago.  The temperatures they left were in excess of 100F, and they
came here to temperatures of about 60F or less.  I stored them in a garage,
since they were dormant, returning two weeks later to find the most amazing
mass blooming I have ever seen, especially of L. radiata.  The flowers were
a bit pallid, since they had no light, but were lovely nonetheless.  This
would seem to indicate that it was the temperature drop - in this case quite
a significant one.
