OriginEurope

The Field Elm cultivar Ulmus minor 'Purpurascens' was listed by Lavallée[1] in Arboretum Segrezianum (1877)[2] as U. campestris var. purpurascens (purpurea), but without description, and later by Schneider in Illustriertes Handbuch der Laubholzkunde (1904).[3][note 1] Krüssmann[4] in Handbuch der Laubgehölze (1962) identified it as a cultivar.[5]

Schneider, Henry,[6] and Green[7] believed the cultivar 'Myrtifolia Purpurea', which was also first listed in 1877, a synonym of U minor 'Purpurascens'.

Description

[edit]

The tree has small leaves approximately 25 mm long, rough above, downy beneath, tinged with purple when young, but turning dark green later.[8] The twigs are downy. Green noted that the tree usually remains small.[6][7]

Pests and diseases

See under Ulmus minor.

Cultivation

[edit]

A grafted tree at Kew Gardens labelled U. campestris var. purpurascens, planted in 1885, was 20 ft tall by 1912.[6] (For specimens supplied by the Späth nursery as U. campestris myrtifolia purpurea, see 'Myrtifolia Purpurea'.)

Notable trees

[edit]

Three trees survive in Hove, one of them the UK champion (see 'Accessions'). Until 2018 one was misidentified as the large-leaved purple elm U. × hollandica 'Purpurascens'.[9]
