Such a beautiful tree. The first to change color in my garden, at the beginning of September! The colors start off peach and turn hot orange and then red. Stunning.
This is a very slow growing tree, unlike the smokebush Cotinus coggygria.
This plant started growing from a stone wall I built about 20 years ago and I just figured that the seed came from all the mulching I do every year from wood chips I get from tree service.
I cut it all the way back every year --and it just keeps coming ! I like the purple much more. ( z 5 )

I bought my current property seven months ago and have finally identified my Cotinus obovatus by emailing a photo to Rhys Caunter at Trees R Us here in New Zealand! My tree is very, very old. It has fallen down some time ago. Of the three original branches, two remain growing. I'm from Nova Scotia originally and have been sort of stuck here due to the Hague Convention for the Child for a long time so to find another NA native here is just, like, far out, man!!! :)

An intresting small, frequently contorted tree of limestone uplands that is common in some places here and rare to nonexisistent in others. Flowers are not very showy. The second or third largest specimen in Madison County, Alabama resides in the woods behind my house.

This species grows bigger than the more common purple smokebush. Its leaves are green, its "smoke" is much bigger, more colorful, and persists into winter, giving a long season of interest. Seeds readily germinate when ripe, they can be sown immediately or stored; stratification not needed.
