| Origin | Europe |
The Wych Elm cultivar Ulmus glabra 'Corylifolia Purpurea' was raised from seed of 'Purpurea' and described as U. campestris corylifolia purpurea by Pynaert in 1879.[1] An U. campestris corylifolia purpurea was distributed by the Späth nursery of Berlin in the late 19th and early 20th centuries. Green listed 'Corylifolia Purpurea' as a form of U. glabra.[2]
Description
According to Pynaert, 'Corylifolia Purpurea' had large purplish leaves resembling those of Hazel, with the purple colour persisting into autumn on outer branchlets.[1]
Cultivation
No specimens are known to survive. One tree obtained from the Späth nursery in Berlin was planted in 1893 at the Dominion Arboretum, Ottowa, Canada.[3] A specimen at the Ryston Hall , Norfolk, arboretum, obtained from the Späth before 1914,[4] was killed by the earlier strain of Dutch elm disease prevalent in the 1930s. Three specimens were also supplied by Späth to the Royal Botanic Garden Edinburgh in 1902 as U. campestris 'Corylifolia purpurea', and may possibly survive in Edinburgh as it was the practice of the Garden to distribute trees about the city (viz. the Wentworth Elm).[5]
U. glabra occasionally produces purple-flushed new leaves; an elm in the gardens of the Hedvig Eleonora Church, Östermalm, Stockholm, incorrectly listed as U. procera 'Purpurea', appears in form, fruit and foliage to be a wych elm with a purplish tinge to some leaves.[6] A similarly misnamed 'Purple English Elm' remains in cultivation in Estonia.[7]
