Chuck, I've gotten a few plants in the mail in the spring before bloom
season - they've done fine for me.
Some were from Christy Hensler on the west coast. One put up a normal
bloomstalk a week or so after arrival. But hers were ones she was
recommending as especially tough survivors, so that's not a fair comparison.
But the others were from Blue Jay (I paid a premium to get them to send
it out of season). It did fine, but the cultivar wasn't one that liked
it here all that much.
Then there are the ones from Blyth that come from Oz via Robin Shadlow.
Not a fair comparison since those are mature and 'dormant' when
shipped. Depending on cultivar, some of those do fine.
Seems like there have been a few others - maybe from Betty, which would
also be pretty strong genes for survival here.
