I love how fast this shrub grows here for me, little seedlings that germinate one spring will flower for me in the second spring, often times on small 1 foot tall little plants. They bloom profusely and are a sight to see all open at once, if you don't want seeds to save or seeds to drop, AND unless you have a thick layer of mulch, YOU MUST snip off the dead flowers or they will reseed everywhere under the mamma plant. They come true from seed. Overall, I love it in my gardens and wouldn't trade it for anything :)
