Didn't know it was possible!
Earlier this year I dug up and moved my 2 wintersown Lavatera plants. That transplant went well even though it was mid August and hot. Well over the last 2 weeks I've noticed some small plants growing in the spot I took them from, but they were still too small at first too tell what they were. HAHAHA! The three small shoots turn out to be Lavatera!! I must have left some root behind which split into forming two plants and the other plant that was dug out just sprouted one single shoot from left behind root. I didn't know that was possible especially since they had only been in the ground since May and I was pretty dilligent about getting the entire small rootballs; which is why they probably settled so well in the new bed. I know lots of plants can re-sprout from left behind pieces of root...just didn't expect it from 4 month old plants LOL!! Gardening never ceases to amaze me :D
