Taxon Description:
A familiar deciduous tree of the largest size, frequently reaching 30 m or more, this species is so commonly naturalized in Britain that it is often thought to be native but is easily distinguished from our native species (Q. petraea and Q. robur) by the downy shoots, the persistent stipules around the buds and the long scales on the acorn cup. The leaves are oblong to oval in outline, to 12 cm long and shallowly or deeply cut into pointed or rounded lobes. The acorns are up to 3 cm long and ripen in the second year in a cup covered in slender scales. The leaves are extremely variable in shape and some forms, with shallow rounded leaf lobes or short petioles, have been thought to be hybrids with Q. robur. Unfortunately this species is secondary host to the wasp that causes knopper gall, which disfigures so many acorns on Q. robur. Introduced before 1735. A splendid tree, 36 m tall with a full crown, is at Knightshayes Court, two miles from Chevithorne Barton.There were no Turkey oaks at Chevithorne Barton before we started collecting but several have since been planted, the tallest of which is about 15 m.
