Sessile Oak
Ironwood Tree

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.

Ironwood Tree is one of the strongest and most resilient trees you will find in North America. In fact, it has the hardest and most dense wood of any North American tree. Prized for its oval shaped canopy and showy winter trunk, this striking shade tree will make a beautiful addition to any yard. Make sure you do not plant near roads as it is highly salt sensitive.
