x Laburnocytisus adamii or a freak?

[gibbon]

Pruned this hybrid laburnum this week to remove some very deformed branches. The offending branches curled back around like a claw and just kind of went wild. Any idea what causes this? I'm sure its not normal for a x laburnocytisus adamii? at least thats what I think it was.

 

Sorry about the poor photos, I only took them on my phone as an afterthought

Had the same response from a plain laburnum last year. Perhaps it's standard practice for laburnum and that in yours the lab's taking over from the broom, which happens with age apparently, the tree not being a true hybrid but a mixture.

I thought that it was some kind of re-verted foliage, but I've never seen this claw like growth on any other laburnum

I've seen this before, several times, not sure what it is thoiugh.

The one I mentioned did just this; the regrowth was all over the place - looks a right mess!

I think its a fasciate mutation.
