- Description
-
Darlington Oak is an evergreen to a tardily deciduous native oak tree which grows rapidly to 60 feet or more and has a life span of about 50 years. In nature, it can be found in sandhills, dry hammocks, and other dry, sandy soils. It makes a good shade or street tree, is moderately salt-tolerant and prefers dry sandy soils.
The leaves generally stay on the tree until new leaves are formed in spring. The acorns are biennial and loved by wildlife. It is a great tree for use in naturalized areas.
It is a host plant for the larvae of the Imperial moth (Eacles imperialis), as well as numerous butterflies, including Banded hairstreak (Satyrium calanus), Edward's hairstreak (Satyrium edwardsii), Gray hairstreak (Strymon melinus), White-m hairstreak (Parrhasius malbum), Horace's duskywing (Erynnis horatius), and Juvenalis duskywing (Erynnis juvenalis).
The relatively short life span of the tree and its susceptibility to diseases and rot with maturity make it somewhat less desirable for home use. However, it does grow fast to provide quick shade.
Consider Planting: Q. virginiana for better longevity. See other native oaks listed to the left for the southeastern USA.
Insects, Diseases, and Other Plant Problems: Laurel Oak disease, a fungal pathogen identified in 2000, is deadly for this tree. Mites, gall wasps, leaf miners, and tent caterpillars can occur.

- 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. Mildly resistant to deer. Acorns are an important food source for wildlife. Oaks are a host plant for moths and butterflies.
