Ulmus

Leaves of 'Berardii'
Cultivar 'Berardii'
Origin Metz, France

The elm cultivar Ulmus 'Berardii', Berard's Elm, was raised in 1865 from seeds collected by Simon-Louis from large trees growing on the ramparts at Metz.[1] As with 'Koopmannii', 'Berardii' is treated in some north Eurasian treatises as a cultivar of the Siberian Elm Ulmus pumila. Green, who had examined dried specimens of the plant, also considered it "as possibly a form of U. pumila".[2]

Description

'Berardii' made a very bushy shrub or small tree, with minute, very dark almost black glabrous leaves 1218 mm long, deeply incised by relatively few teeth and was said to be like those of Planera crenata.[1][3] Krüssman noted that it was late to come into leaf.[4]

Cultivation

The tree is not known to remain in cultivation. A specimen was once grown at Kew Gardens, obtained from the Späth nursery before the First World War.[5] One tree was planted in 1893 at the Dominion Arboretum, Ottowa, Canada.[6] Three specimens were supplied by the Späth nursery to the Royal Botanic Garden Edinburgh in 1902, and may possibly survive in Edinburgh as it was the practice of the Garden to distribute trees about the city (viz. the Wentworth Elm).[7] The current list of Living Accessions held in the Garden per se does not list the plant.
