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?
Thanks

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. http://ecosystems.psu.edu/research/centers/private-forests/news/2012/winter-leaves-that-hang-on


Thanks so much
