Gray Oak Tree

Gray Oak Tree

The gray oak is a handsome evergreen oak with the most pleasing blue-grey leaves, native to the Southwest and down into Mexico. It’s currently an uncommon tree in the nursery trade but hopefully that changes as gardeners fall in love with its beautiful form, evergreen foliage and adaptability. We are growing a grafted clone called ‘Ecinoso’ that was discovered at 6400′ in Ecinoso, New Mexico.
