Description

A slow-growing tree, forming an unbroken, broad pyramidal crown, with small, glossy, dark-green leaves persisting for several weeks longer than most in autumn.[3]

Cultivation

Saplings grown from seed by Haarlem head forester J. Kollerie were first planted along a new canal in the city in 1891.[2] An U. campestris 'Haarlemensis' was cultivated in the Poort Bulten Arboretum in the 20th century (see External Links). No specimens are known to survive.
