Hybrid Oak

Quercus x rosacea (= Q. petraea x Q. robur)

Hybrid Oak (Quercus x rosacea) leaves and acorn

The parents of this hybrid Quercus petraea and Quercus robur can be quite variable in themselves, and thus the resulting offspring Quercus x rosacea may also be fairly variable having varying strengths of its parents which can make identification somewhat confusing, even more so when these characteristics appear mixed as in some specimens. For example as in the length of the petioles (leaf stalks) and the peduncles (acorn stalks). It flowers May to June. It can grow up to a height of 25m (82ft).
