Re transplanting...
Rose of sharon are easy.
I've cut limbs off the trees and grown new plants when I stuck them into the soil.
The single flowered type can be seedy, and when they get enough moisture, can produce plenty of seedlings.
The double flowering types don't produce as many seed, but the pollinators and hummingbirds seem to prefer the single flower type.
Up in Chicago, I'm not sure that an autumn planting is correct, due to the likelihood of frost heave pushing the plant back up out of the ground.
Autumn planting is correct for the south, but at your house?
