Quercus lyrataAlso known as:
swamp post oak,
swamp white oak,
water white oak
Quercus lyrata is a slow growing, deciduous shade tree with a round, open form that can reach a height of 50' with a 40' spread. This is a sturdy tree that naturally develops a strong trunk. It has leathery, green, narrow leaves that are deeply lobed and turn rich shades of brown in fall. The flowers are unremarkable and born on catkins. The roundish acorns are distinctive for they are almost entirely covered by the cup, hence the common name overcup oak. These will not be produced until the tree is 20 to 25 years old.
Native to the southeastern lowlands of the U.S., overcup oak is adapted to seasonal flooding. Though it tolerates both "wet feet" and drought, it does best in well drained, rich, acidic soil. It will require little or no pruning to develop a strong trunk. The lower limbs can be pruned at the trunk to provide desired clearance. Though it is not commonly sold commercially, it is ornamental and easy to grow in virtually any soil. Blooms in April or May. Zones 6-8
Propagate from seed.
Mature overcup oak produce large quantities of acorns, which provide an important food source for the local wildlife, both large and small. Though the wood is dense, heavy and strong, it is usually plagued by defects and is of little commercial value.
