pbs Digest, Vol 31, Issue 5-- Lycoris squamigera; Hymenocallis caroliniana

Hello all: One stalk of squamigera in bud and up about 30"-- here in the 
Chicago area.  It has 6 buds, but I recall seeing more on other stalks 
historically. Does anyone have a maximum known number?.-or what's the 
largest number that anyone on this list has seen.

Attempts by me to self these even with an assisting solution of 2-4D into 
the bottom of the flowers for two years running now, has produced balloon 
pods, and some apparent seed which rapidly dried out and revealed themselves 
as having no embryos .  They are certainly self-sterile which is not a 
surprise--being triploid.  (Bow in Jim Waddick's direction. for the 
information)


I also have two Hymenocallis caroliniana (if they're true to name) that are 
in bud which surprised me because I got them in June with no leaves.  I put 
them in the bottom of a 10 gal. paint drum with a little peat outdoors and 
some moisture so that they wouldn't dry out before I got around to planting 
them.   Two days ago, I noticed that 2 of the 7 had floweor stalks on them. 
What is the usual bloom season for these?  I thought that it was spring and 
that they didn't go dormant until late fall.  (These had been  dug from the 
wild , trimmed for sale and shipped with fleshy roots., which I think pushed 
them into a artificial dormancy. (I bought them on eBay.)
