Looks Like Cerces on Steroids
Hi. There isn't a question here. Are you wanting to know the ID of this plant?
How do you know the hardiness?
So sorry, I am new to this site. We don't know what the plant is. The only info I was given was that it is not hardy in zone 8 and grows very tall when grown inside. Not much for you to go on, I know.
That's okay! I will work on getting an ID for you. You are right, it looks like a Cercis on steroids. Have you seen a flower on it? Could you get a pic of the stem?
I will contact the woman who showed it to me and forward the info. Sorry - Cerces.
Nothing to be sorry for! I will see what I can find out about it!
