A year or two ago I described the problems I was having with Chasmanthe
floribunda in my zone 7 garden. To make a long story short, it grew but did
not bloom. Back then I was storing them dry inside during the winter and
planting them out for the summer. At that time various suggestions were
made. One was that it perhaps needed more heat. That suggestion I'm sure was
made by someone who has never had the dubious pleasure of enduring summer in
Maryland. My own thoughts leaned the other way: perhaps it needed a
cool/cold period.

With that in mind, I planted the corms outside in a protected spot where
they could remain permanently - or die.

Last year they came out of the ground too early and were severely cut by
cold. This year, they are now just emerging. I'll protect them if necessary,
but I'm getting the impression that little by little they are adapting to
our local conditions.

I'll let you know when they bloom (next year?).
