Quercus phellos
Willow Oak is an attractive, medium-sized, deciduous tree, which offers good texture and form. It is monoecious; insignificant separate male and female catkins appear in spring. It has cascading, narrow, willow-like leaves, which turn yellow, bronze-orange, yellow-brown, or russet-red in fall. It tolerates a wide range of soil conditions and some salty conditions. The acorns provide food for birds and wildlife. Oaks are host to numerous beneficial insects, which in turn provide food for birds. Willow Oak is a host plant for butterfly larvae (caterpillars) of White M Hairstreak (Parrhasius m-album). It provides nesting space, cover, and shelter for wildlife. Use Willow Oak as a street tree or shade tree, and in parks or in natural areas.
