- Description
-
Shingle oak is a deciduous tree in the oak family (Fagaceae) native to central and upper southern USA. It can be found growing in uplands with good drainage and less often along lowland streams. It was previously used to make shingles, hence the common name.
Shingle oak has strong wood, a broad pyramidal crown and grows 50 to 100 feet tall. With age the crown becomes broader and more open. It tolerates a wide range of soil types and prefers well-draining soil in full sun to partial shade. Propagation is by seed.
Lower branches are widely spreading or slightly drooping, while upper branches are upright. The leaves are lobed, 3 to 6 inches long and turn yellow to russet in the fall. The acorns mature the second year.
Use shingle oak as a shade or street tree. Oaks are wildlife-friendly and can be planted in naturalized areas.
Insects, Diseases, and Other Plant Problems: Insect pests include scale and two-lined chestnut borer. Oak wilt is a potential disease problem. Galls caused by mites or insects are common, but not harmful. See pests and diseases of oaks to the left.

- Wildlife Value:
- Oak trees support a wide variety of Lepidopteran. You may see Imperial Moth (Eacles imperialis) larvae which have one brood per season and appear from April-October in the south. Adult Imperial Moths do not feed. Banded Hairstreak (Satyrium calanus), which have one flight from June-August everywhere but Florida where they emerge April-May. Edward's Hairstreak (Satyrium edwardsii), has one flight from May-July in the south and June-July in the north. Gray Hairstreak (Strymon melinus), has three to four flights in the south from February-November and two flights in the north from May-September. White-M Hairstreak (Parrhasius m-album) has three broods in the north from February-October. Horace’s Duskywing (Erynnis horatius) has three broods in Texas and the deep south from January-November, and two broods in the north from April-September. Juvenal’s Duskywing (Erynnis juvenalis) has one brood from April-June, appearing as early as January in Florida. Very high wildlife value. Many birds and mammals eat the acorns. It is a host plant to several moths and skippers. Many insects are attracted to the tree, which in turn provides food for birds and other insect-eating animals.
