Reversion

[arbwork]

I am fascinated and intrigued by plant cultivars ability  known for a particular leaf shape, colour, or other striking characteristic to try to ‘revert’ back to a different form found in the plant’s parentage, here Acer platanoides Drummondii recent

That's striking, but is it strictly reversion? Reversion is, I understand, losing the abnormality of the lack of chlorophyll and turning back green. The plate with the divided green leaf (white one side of the midrib/green the other) must be reverting on the side that's green and whatever the opposite of reversion is on the other. I.e turning completely white.

 

I don't understand the white leaves that you see on hollies, usually epicormic type shoots around a secondary stem stub. They're not photosynthesising (or are they) but are able to grow - so must be drawing energy from the parent tree. I don't get how/why the parent continues to supply the workshy growth, although there must be some mechanism in place because the never seem to reach much more than a certain size.

 

Have you thought of trying to strike cuttings from that 50/50  branch?
