Description

Overcup Oak is native to central and southeast North America. In spite of its natural occurrence where periodical flooding is typical, overcup oak grows well on sites with better drainage and soil texture. It gets its common name from the distinctive bur-like acorn cup that typically encloses 2/3 to almost all of the nut. This renders it buoyant in flood areas.

Plant this tree in low lying areas or along streams, rivers or ponds.

 

Insects, Diseases, and Other Plant Problems: Oaks, in general, are susceptible to a large number of diseases, including chestnut blight, shoestring root rot, anthracnose, oak leaf blister, cankers, leaf spots, and powdery mildew.  However, this tree is resistant to oak wilt. Potential insect pests include scale, oak skeletonizer, leaf miner, galls, oak lace bugs, borers, caterpillars and nut weevils.
