Quercus palustrus - Pin oak
Description: Pin Oak is a medium-sized, deciduous tree of the red oak group. It is monoecious; greenish-yellow flowers bloom on separate male and female catkins in April. Its dark green leaves have five bristle-tipped lobes, and turn deep red in fall. It tolerates poorly-drained soils and some flooding. It may take 15-20 years until the tree matures to bear acorns, which provide food for birds and wildlife. Oaks are host to numerous beneficial insects, which in turn provide food for birds. Pin Oak is a host plant for butterfly and moth larvae (caterpillars), including Gray Hairstreak (Strymon melinus). It provides nesting space, cover, and shelter for wildlife. Use Pin Oak as a shade tree in the yard, park, or natural area, or as a street tree.
