TheField ElmcultivarUlmus minor'Viminalis Pulverulenta'(:'powdery'), also known as 'Viminalis Variegata',[1]a variegated form ofU. minor'Viminalis',[2][3]was first mentioned byDieck,(Zöschen,Germany) in 1885 asU. scabra viminalis pulverulentaHort.,but without description.[4]Nursery, arboretum, and herbarium specimens confirm that this cultivar was sometimes regarded as synonymous withU. minor'Viminalis Marginata'[5](see Cultivation), first listed in 1864, which is variegated mostly on the leaf margin. It is likely, however, that 'Pulverulenta' was theU.'Viminalis Variegata',Variegated Twiggy-branched elm,that was listed and described by John Frederick Wood, F.H.S., inThe Midland Florist and Suburban Horticulturist1847 and 1851, pre-dating both Kirchner and Dieck.[2][3]Wood did not specify the nature of the variegation.
Description
[edit]Dippel(1892) described 'Viminalis Pulverulenta' as having leaves streaked with both white and yellow.[6][7]Wood (1847 and 1851) described 'Viminalis Variegata' as having small leaves and slightly pendulous branches clothed with little shoots, adding that the leaves "occasionally evince a disposition to revert to the green state".[2][3]

Pests and diseases
[edit]'Pulverulenta' is very susceptible toDutch elm disease.
Cultivation
[edit]Wood (1847, 1851) considered 'Viminalis Variegata' "a singularly pretty variegated small tree".[2]As a lawn tree, "When grafted standard high it is one of the prettiest trees imaginable for a single specimen".[3]One, listed asU. campestris viminalis variegata,grew in the Royal Victoria Park,Bath,in the mid-19th century.[8]There was a specimen at Kew Gardens in the early 20th century.[9]Three trees were supplied by theSpäth nurseryof Berlin to theRoyal Botanic Garden Edinburghin 1902 asU. campestris viminalis marginata,shown by herbarium specimens to have been 'Pulverulenta' or 'Variegata'.[1]They may survive inEdinburgh,as it was the practice of the Garden to distribute trees about the city (viz. theWentworth Elm);[10]the current list of Living Accessions held in the Gardenper sedoes not list the plant.[11]TheUlmus campestris viminalis marginatasupplied by Späth and planted in 1897 at theDominion Arboretum,Ottawa,Canada, is likely also to have been 'Pulverulenta' or 'Variegata'.[12]Ulmus Viminalis variegata,"a variegated variety of good growth", appeared in early 20th-century catalogues of theGembrookor Nobelius Nursery nearMelbourne.[13]
The tree is now extremely rare in cultivation. A specimen that stood inHighnam Court,Gloucestershire,till at least 1969 was incorrectly labelled'Viminalis marginata',[14]as is the tree that grows atBatsford Arboretum,Gloucestershire (2023). The Batsford specimen is grafted on a non-suckering stock.[15]Pressed leaves from the Highnam Court tree were sent to theKew Herbariumin 1969 by Eric W. Pymont (1925–2015), Head of the Horticulture Department at the Gloucestershire College of Agriculture, Hartpury House.[16][17]
