You are right they are meant to be large shrubs and and there's a high prob. Of breakage if located in a high wind area. Just like buddleia (ex. or any tecoma.
It's no longer tied (btw WIND actually tore the ties) but have not removed the pole yet.
On a separate subject, I do a Major cringe when I see a tree/shrub that has been staked with a fence post, never removed and plant just growing around it. Why won't people remove them???
