Sessile Oak is a large, long-lived deciduous tree with a wide, rounded crown. It is an important host plant for many pollinators, especially in its native range. Its acorns serve as a valuable food source for birds and small mammals, providing strong ecological value. It differs from many oaks as the leaves grow on longer stalks, whereas the acorns are stalkless. It can live for hundreds of years, with some surviving over 1,000 years in ideal conditions. As it matures, the tree develops a rugged, gnarled structure that provides heavy shade and a distinctive appearance.

More drought-tolerant than other oaks and does not do well in waterlogged or compacted soils.
Native to Europe and is the national tree of Ireland.

Note: Most Oak species can be considered toxic for many animals.

Thornless Honey Locust makes an excellent shade tree with its lacy foliage and dappled shade. The leaves are honey-yellow, light and airy, providing interesting color and texture to your landscape.
