Cultivation
Now extremely rare in cultivation, one tree grows at Batsford Arboretum, UK. [2] Three specimens supplied by the Späth nursery of Berlin to the Royal Botanic Garden Edinburgh in 1902 as U. campestris 'Viminalis marginata' [sic], shown by herbarium specimens (see External links below) to have been 'Pulverulenta' or 'Variegata', may survive in Edinburgh, as it was the practice of the Garden to distribute trees about the city (viz. the Wentworth Elm);[3] the current list of Living Accessions held in the Garden per se does not list the plant.[4]
