I've got maybe 15 young plants that I grew from seed. About 6 of them have grown upright and are about 30" tall, the rest seemed to lose their growth center and have branched, being about 24" tall. They have heavy stalks, not spindly at all. They're growing in full Tx sun from about 10:00 to 3:00, semi shade earlier, complete shade for late afternoon. When can I hope to see blooms??? TIA Sheila :-)
