Theories - Late Summer bulbs(Lycoris), rain etc.?

Jim W. and all,

Here, we received over 4 inches of rain in a week's time in about the third 
week of August.

Our Lycoris made a weak attempt at flowering during the last week of July 
and the first week in August.  Starting within a few days of the heavy 
rain, the Lycoris began sending up new scapes from places where there had 
previously been no flowering in July and August this summer.

This late burst is definitely heavier -- more scapes, more flowers -- than 
the first flush was.  So I think I see confirmation of Jim Waddick's rain 
hypothesis, at least in my garden and with the heavy rain we received in a 
short period of time.

Now some of the Colchicum are starting to bloom, at least in a few 
spots.  The Hymenocallis occidentalis did not bloom at all until after that 
rainfall.  A few scapes are up and in flower on them now.

So what are we to conclude?  That resuscitation after a drought is 
dependent on the amount of rainfall received?  Possibly so.
