The Sessile Oak (or Welsh Oak) has leaves that are broad for an Oak and evenly lobed. The flowers appear as small green catkins in the spring, with the acorn developing over the next few months. In autumn time the leaves turn brown before falling. The significant differences from the English Oak include leaves that are stalked and acorns that are stalk-less (sessile) and hence the common name. Quercus petraea is a useful choice for coastal locations and will tolerate acid soils.
