01-12 – The Haas Oak (Quercus haas) is closely related to the pedunculate European oak (Quercus robur) but has larger leaves and pubescent twigs. It comes from the Caucasus region and is considered part of the Quercus robur taxonomic group. This Haas oak was grown from the first specimen ever introduced into cultivation, in 1855, at the Museum of Paris, France. The species was formally introduced elsewhere from there in 1870 but it remains very rare in cultivation and is seldom seen even in arboreta.
