Curly-Q Fasciation On Continus coggygria

Pruning out the dead wood this week, I noticed this peculiar stem.

Here, this smokebush (Cotinus coggygria) had one curly branch. Removed it to take a photo.

Fasciation has made tissue grow faster on one side, and then the other side (inner tissue) at a normal rate. This caused the curling effect. Cool.  Have a look at a previous post that explains, Fasciation.
