- Description
-
Nuttall oak is a decidous tree in the Fagaceae (oak) family. It is native to wet, heavy, bottomland soils in floodplain forests along the gulf coasts and up the Mississippi river basin. Nuttall oak is a beautiful, large, shade tree and provides rich, red-orange fall color. It grows up to 80 feet tall with a 50-60' spread forming a large, stately tree with a narrow, rather open, rounded canopy that is somewhat reminiscent of Red Oak.
Well adapted to a wide range of soil types, it does well in low moist areas but is also drought tolerant once established. The crown spreads with age becoming round at maturity. The 4-8" long deciduous leaves are deeply-lobed (more so that Quercus rubra) and have bristles on the tips of some lobes. A lovely dark green during most of the year, this plant puts on a vivid display of brilliant red to red-orange fall and winter foliage, providing a dramatic landscape statement. Fall and winter coloration varies from year to year in USDA hardiness zones 8 and 9. During the winter the bare tree provides interesting branching patterns.
This large shade tree is highly adaptable to urban conditions and does well as a street tree. The acorns mature over 2 seasons and attract birds and small mammals and the tree is a larval host plant for many moths and butterflies making it an excellent choice for a specimen or shade tree in a wildlife garden. 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).
Insects, Diseases, and Other Plant Problems: No serious pests or diseases.

- 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. Birds and mammals eat the acorns.
