What it's good for, and what it isn't

A large oak with a broad crown, dark green leathery lobed leaves and distinctive acorns in shaggy, mossy cups. It is one of the most heat and drought tolerant oaks and grows on limy or poor soil too, which makes it a good shade-giving specimen for big gardens and parks. It needs a lot of room, the leaves that hang on into late autumn and winter and the many acorns mean work, and keep the acorns away from dogs.

Watch out for
It is a confirmed host of the oak lace bug: the insect, introduced from North America, reached Central Europe in the 2010s and has caused mass damage since, and its feeding makes the foliage fade and yellow by midsummer. It is also one of the preferred hosts of the oak processionary moth: the stinging hairs of the caterpillars cause severe rashes and breathing problems, and nests should be removed by professionals only. The trunk can crack in hard frost, but the tree is not prone to powdery mildew. It does not suit paved or cramped sites.
