The swamp oak (Quercus palustris) is a monoecious tree of the Napa family (Fagaceae), which occurs naturally in the river valleys of the north-eastern United States and reaches a height of 25 m there. Male and female flowers appear separately on the tree. The tree has been planted in Europe since the end of the 18th century. In the Netherlands, it is planted quite often along streets and in parks and public gardens in built-up areas. The tree is unsuitable for calcareous soils and contrary to what the name would suggest, the tree is less suitable for wet, swampy soils. However, the tree can withstand flooding for a short time. The leaves have a strikingly beautiful, deep red autumn colour. The quality of the wood is less compared to that of the other Oak species.

Botanical name: Quercus palustris
