It's an early spring/late fall cycle rebloomer. Pretty reliable here,
but I sent starts a couple of times to Atlanta where they died, & didn't
rebloom for the Spoons, so with its other faults, decided not to
introduce it.

It does ok, I think, the other places I've sent it (KY & Nebraska), but
Loic is generous saying the texture is a "bit" thin ;-). Plus falls are
not quite as wide as I'd like & stalks not tall enough (good for Loic,
not for me).

On the plus side, it can make a pretty show with a bunch of stalks
blooming, is reasonably strong and healthy, and has at least once
produced more than 30 blooms on one stalk. And will continue to bloom
reasonably well without being dug and re-set.

<Yes Chuck, "Cloud Shadow" is a garden name, Linda still hesitates to
register it.
Even if the texture is a bit thin, >
