Quercus robur 'Fastigiata' is a long-lived oak (to 800 years, and more) that was first discovered growing wild in a forest in Germany and was propagated by grafting in 1783. It is native to most of Europe, and to Anatolia to the Caucasus, and also to parts of North Africa and grows to an altitude of 0- 1000m.
It is an upright, columnar, deciduous tree which eventually matures into a dense elongated oval shape with a short trunk. It grows moderately fast to 30+ m high with a trunk that is up to 3 m in diameter.
The 5-12 cm long by 3-8 cm wide leaves maintain their dark green colour throughout the year until they turn brown in autumn. They often remain on the tree for some time before dropping. The attractive, dark grey-brown bark is deeply ridged and furrowed, and the 1.5-4 cm acorns persist on the tree throughout the winter.
In spring yellow-green male catkins form acorns which are 2-6 cm long.
