Quercus ×heterophylla – Bartram’s oak

View prices and availability
Natural hybrid between Q. phellos and Q. rubra that occurs in places where both species are found. Forms a large deciduous tree with an ovate to round crown growing to around 20 m. The bark is grey and smooth until it is quite old. The bark only gets slightly rough on older trees. The leaf shapes vary greatly from lanceolate to oval. It is usually at its widest above its middle. It is either smooth-edged or has 3 to 5 teeth per side. The top of the leaf is glossy green and bare. The underside is lighter and only hairy in the vein axils. In autumn, the leaf turns reddish to reddish brown. It produces only a few acorns which look like the ones on Q. rubra. A healthy, hardy tree that thrives on less fertile soil, provided it is moist enough and not too limy.
