Description
editQuercus laceyi seldom grows more than 35 feet (11 meters) tall, and has a stocky trunk. Its blue-green leaves are oblong and shallowly lobed to unlobed, but shade leaves can be deeply lobed; they most often turn yellow or brown in autumn.[3][5]
Quercus laceyi has often been confused with Quercus glaucoides, which is an evergreen oak native to central and southern Mexico.[4]
Habitat
editQuercus laceyi is often found in association with limestone outcrops.[6]
