canadanna said:So, are all of the semps that send out stolons called rollers?
I don't think that is necessarily true. The 'roller' name comes from the habit of these round chicks being able to detach from the hen and "roll" away from the mother and then start to root elsewhere. Other semps with chicks on stolons can have their chick stay awhile attached to the stolon even after establishing their own roots. Those with chicks that aren't round in shape with clustered leaves don't usually roll anywhere. Just my observations...
I have also observed a trend to plant the Jovi roller plants at the foot of a featured bonsai plant in its container. I've seen this at bonsai shows and bonsai shops. A new way to introduce rollers to the public?
