| 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.[1] Krüssman included it in his manual as an Ulmus glabra cultivar,[2] but the plant's long, slender 2 cm petiole[1] (see herbarium specimens below) is not a feature of U. glabra, and is even less likely in a shrub form of this tree.
The Späth nursery of Berlin marketed Ulmus montana monstrosa in the late 19th and early 20th century, listing it separately from Ulmus montana nana,[3] sometimes referred to as Ulmus scabra [:glabra Huds.] f. nana monstrosa Schneid.[4]
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.[1]
Cultivation
No specimens are known to survive. U. montana monstrosa was introduced to the Dominion Arboretum, Ottawa, Canada, probably from Späth, in 1899.[5] A specimen obtained from Späth as U. montana monstrosa and planted in 1916, stood in the Ryston Hall arboretum, Norfolk,[6] in the early 20th century.[7]
The shrub elm sold in the Netherlands as 'Monstrosa' appears from photographs to be the cultivar 'Nana'.[8] 'Nana Monstrosa' was an old synonym of 'Monstrosa'.[4]
