Cultivar 'Monstrosa' People also search for Ulmus 'Nigrescens' | Origin France | |
The elm cultivar Ulmus 'Monstrosa' is believed to have originated in France, where it was listed without description as a form of Field Elm, Ulmus campestris var. monstrosa. Krüssman included it in his manual as an Ulmus glabra cultivar, but the plant's long, slender 2 cm petiole, if correctly reported, is not a feature of U. glabra, and is even less likely in a shrub form of this tree.

Description
'Monstrosa' is a compact shrub, with branchlets often fasciated, and leaves 5–8 cm long, partly pitcher-shaped at the base, and on slender stalks < 25 mm long.
Cultivation
No authoritatively identified specimens are known to survive. A 'Monstrosa' at the Ryston Hall [2], Norfolk, arboretum, obtained from the Späth nursery in Berlin before 1914, was killed by the earlier strain of Dutch elm disease prevalent in the 1930s. The shrub elm sold in the Netherlands as 'Monstrosa' appears from photographs to be the cultivar 'Nana'.
