- Description
-
Bartram Oak is a large deciduous tree in the Fabaceae (beech) family. It is found growing in the central and eastern United States as a naturally occurring hybrid between Q. phellos and Q. rubra where both trees are found to grow naturally. Being a hybrid, the leaves can be variable even on the same tree. The acorns tend to be small and nearly stemless. As with all oaks, it is a wildlife magnet for birds, butterflies, moths and mammals.
Plant it in the full sun in moist acidic soils. It does not need overly fertile soils to thrive. The crown is rounded with an open branching pattern and makes a great shade tree for a large yard, park or other public areas.
