Since cultivars should all be clones, I would expect the amount of leaf dop to be essentially the same on all plants wtihin a cultivar.

You are correct in that the degree of leaf retention is related to both genetics and environmental conditions. You will find variation from one plant to the next within a particular cultivar or genus. Look for an upcoming post where we highlight particular hamamelis with no/low leaf retention and fragrance.

I am curious about the Hamamelis mollis ‘Early Bright’ photos you’ve posted. I always assumed that the degree of leaf drop was primarily a factor of the cultivar. Apparently environmental conditions also play a role – nature vs. nurture. I realize the variables might be too complex to easily chart, but has anyone been looking at the factors affecting leaf drop? It would be great to plant a Witchhazel with some expectation of being able to appreciate the flowers on naked branches.
