Smooth Sumac

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.

Smooth Sumac is an excellent shrub for both its ornamental appeal and tolerance of difficult planting sites. You'll love the attractive pyramidal spikes of hairy, red berries that emerge on female plants and the fern-like foliage that covers both male and female varieties.

Ensure you give Smooth Sumac enough space to spread out due to its high suckering nature. While not ideal for small, urban yards, this shrub will make a stunning border along a woodland edge or roadside.

Note:These plants typically reach maturity and make their sex easily known (females producing fruit) in their 3rd or 4th year of growth. Our seedlings are too young to identify their sex.
