More like a tree than a bush. I bought kine as a plant about 2' and the secomd year it came back about 4 feet and the flowers were really big the second year. I am going to try to grow the seeds myself for the first time so I don't have any personal advice about that et. Thanks.
i grow these from seeds, the flowers will get as big as dinner plates.... going to bid on this one as i dont have the solid pink.. i cut mine back so it is a bush ..
