I got these blooming non stop for months except Al Greenberg which just started last week and has five blooms so far, it was so tiny when I first got it about 2-3 months ago. The two little leaves were on it dried out by the time I got it home, it took awhile to settle in and grew big before I knew it.
Dauben was a tiny baby one too but it grew like weed and have at least three flowers a day for months and still going and going like you know what. I wasn't impressed with it at first because its lack of color but growth rate and numbers of blooms sure more than make up for it.
