Quercus phellos

Willow oak

Willow oak. Young, emerging foliage & dangling catkins of staminate flowers.

Fine, narrow leaves create a softer-textured canopy than many other oaks. This native tree grows into a large shade specimen, with small acorns used by wildlife. It suits roomy landscapes and moist sites where its broad crown and spreading roots can develop without crowding.
