These little species glads are about 8" tall, well...that's the largest one that is budding. Many of the species are little guys. Some are said to be fragrant. I think I started these in spring of '07...or maybe it was '08? So 2 or 3 winters I've had them- they just sit dry in the pot over summer and fall, then at some point in winter I see sprouts and stick 'em under lights and start watering and fertilizing lightly.
I did move an Eremurus last year after it had started growing. I contacted Buggycrazy first and asked her if it could be done successfully. Its not advisable, but can be done with care- the roots are fragile and brittle, and spread out flat a foot or more wide. Mine went ahead and bloomed after being moved. The way the roots grow horizontally from the tuberous base makes me wonder if they would even fill a pot with roots the way most plants do? The way the roots just hover an inch or so beneath the soil makes me think they wouldn't- that could be another reason you don't see them sold that way.
Polly, I'd definitely like to try my hand at more species glads, but summer blooming varieties because they're easier for me to deal with. Look at these beauties:
