Description
This plant restricted for shipment to CA, OR
Latin Name: Quercus bicolor
Common Name: Swamp White Oak
Hardiness Zones: 4-8
Mature Height/Spread: Typically grows 50-80 feet (15-24 meters) tall and 50-60 feet (15-18 meters) wide. It features a short trunk and an irregularly shaped crown. The tree is long-lived and has a moderate growth rate.
Soil / Climate: Prefers acidic, moderately wet soil in full sun but can also grow in partial shade. True to its name, it thrives in swampy conditions and is drought-tolerant, adapting to a range of habitats. Native to the eastern United States.
Notes: The leaves are dark, shiny green on top and a paler green underneath, with 5-10 rounded lobes. They are obovate in shape and measure 3-7 inches (7-17 cm) long. In fall, the leaves turn yellow to reddish-purple. In spring, the tree produces inconspicuous yellowish-green flowers in catkins, with male flowers forming 2-4 inch (5-10 cm) long clusters and female flowers appearing as tiny red spikes in leaf axils. The acorns mature in early fall, are about 1 inch (2.5 cm) long, and have a cap covering roughly one-third of their length. The bark is gray, with scales and increasingly prominent fissures as the tree ages. The twigs are smooth and light brown. The Swamp White Oak often hybridizes with the Bur Oak where their ranges overlap in the wild and is among the easiest oaks to transplant.
Problems: In high pH soils, chlorosis may occur. The Swamp White Oak is also susceptible to cankers, anthracnose, leaf spots, and chestnut blight, as well as galls, scale, oak lace bugs, caterpillars, borers, and leaf miners.
Wildlife: The sweet acorns are consumed by squirrels, wild ducks, various non-game birds, and other rodents.
