Are there any plants in Alaska that exhibit marcescence? What are they and where would one find them? Thanks for your response.

There are two species of hornbeam tree that are used for landscape plants that you may find in Alaska: European and American hornbeam.

Hornbeam, oaks, and beech species are known for retaining some of their deciduous leaves, which would qualify as marcescence. Some willows may also retain stipules.

I hope this helps.

Thanks for your response, Dr Matney. Am I correct in assuming from your answer there are no plants native to Alaska, to be found in the wilderness, that are marcescence plants?

It is not exclusive to non-native tree species. The willow family (Salicaceae) includes aspen, poplar, and willows. These are native to Alaska and can display marcescence. Larch trees may also show this trait.

Here is a good article that discusses why you may often see marcescence.

Thanks so much
