  • Photo of Quercus texana (Quercus texanas)

Phonetic Spelling:KWER-kus tek-SAY-nuh

Genus:Quercus

Species:texana

Family:Fagaceae

The Nuttall Oak thrives in a variety of soil conditions, excelling in moist lowlands while also demonstrating drought resistance once it is established. This species is indigenous to the wet, heavy soils found in floodplain forests along the Gulf Coast and throughout the Mississippi River basin. Renowned for its impressive stature, the Nuttall Oak serves as a magnificent shade tree, showcasing vibrant red and orange hues in the fall. It adapts well to urban environments, making it an excellent choice for street planting.

The acorns of the Nuttall Oak take two years to mature and are a food source for birds and small mammals. This tree can reach heights of up to 80 feet, with a canopy spread of 50 to 60 feet. Its large, stately form features a narrow, open, rounded crown that bears a resemblance to the Red Oak, becoming more rounded as it matures. The leaves, measuring 4 to 8 inches in length, are deeply lobed—more so than those of Quercus rubra—and some lobes have bristle-tipped ends. Throughout most of the year, the foliage is a rich dark green, but it transforms into a striking display of red to red-orange in the fall and winter, creating a stunning visual impact. The intensity of fall and winter colors can vary annually in USDA hardiness zones 8 and 9. In winter, the bare branches of the tree reveal intriguing patterns. The acorns, measuring 1.5 inches, are encased in a shallow cup and are favored by local wildlife.

Fortunately, there are no significant pests or diseases that pose a threat to this tree.

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.
Acorns are edible once the tannins have been leached or boiled out.
