Ulmus × hollandica 'Vegeta', sometimes known as the Huntingdon Elm,

wych elm is rare in Huntingdonshire, normally flowering four to six weeks later than field elm, pointed out that unusually favourable circumstances would have had to coincide to produce such seed: "It is possible that, some time in the eighteenth century, the threefold requirements of synchronous flowering of the two species, a south-west wind" (wych does occur in quantity in Bedfordshire), "and a mild spring permitting the ripening of the samaras, were met."[4]

The tree was given the

Chichester Elm by Donn, as Loudon considered the two trees identical. The latter is indeed a similar cultivar, but raised much earlier in the 18th century from a tree growing at Chichester Hall, Rawreth in Essex
.

Description

In areas unaffected by

apetalous flowers are bright red, and appear in early spring. The samarae are obovate, < 25 mm long.[8] Diagnostic photographs of young and mature Huntingdon elms, [2] "Friends of the Meadows and Bruntsfield Links". Archived from the original

A distinguishing feature of 'Vegeta', according to Schneider (1906) and Mitchell (1974), is that the leaf margins to right and left of the petiole start from a vein, not from the midrib.[9][10][11] 'Vegeta'-type leaves from Hinchingbrooke Park collected by Heybroek in 1960 do not share this feature,[12] nor do some old 'Vegeta' cultivars in Oxford and Edinburgh (see ' 'Vegeta'-like cultivars', below). This unusual feature, however, clearly appears in the older cultivar, Chichester Elm,[13][14] and is frequently present in 'Vegeta' elsewhere (see gallery). If indeed the feature distinguishes Chichester from Huntingdon, the former may be more common in cultivation than currently believed, having over time been mis-called "Huntingdon". A 2013 DNA test of old Chichester elms (see under 'Cicestria') did not include a younger nursery-sourced "Huntington" as a "control".[15]

Elwes & Henry[3] and Bean[16] attested that 'Vegeta' suckers freely, but other writers have stated that it does not sucker at all.[6][17] This contradiction is almost certainly owing to methods of propagation: higher class nurseries grafted cuttings onto Wych Elm stock, which would not produce suckers, whilst others simply rooted the cuttings, which would. A comparatively high percentage of the seed is usually viable, but produces variable offspring.[16]

Pests and diseases

The tree was one of four European cultivars found by researchers in The Netherlands to be resistant to the initial strain of

'Exoniensis'. The four were rated less resistant than U. foliacea clone 23, from Spain, later cultivated as 'Christine Buisman'.[18] 'Vegeta' has, however, only a marginal resistance to the later, three times more lethal strain, Ophiostoma novo-ulmi
.

Cultivation

The tree was widely planted in England, particularly between the end of the nineteenth century and the 1930s,

Victoria in 1865[26]
), the tree was marketed by several Australian nurseries in the late 19th and early 20th centuries.

Owing to its resistance to the original strain of Dutch elm disease, 'Vegeta' was planted in large numbers across Amsterdam after the Second World War as a replacement for 'Belgica' (Belgian Elm), but was itself eventually replaced by the Dutch cultivar 'Dodoens' following the arrival of the more lethal strain of DED in the early 1970s.[27]

Notable trees

The UK

Portsmouth, isolated from disease by the sea and urban sprawl. Lincoln has five examples on Yarborough Crescent[32] and in Hull there are four on Brunswick Avenue.[33] One tree survives at the foot of Ladies Mile, Bristol.[34] Another elm is located in Sheffield, as a street tree on the corner of Chelsea Road, and known locally as the Chelsea Elm.[35]

In Wales, one very large tree (NT number 771, last recorded in 1995) stood in the grounds of

Kildangan Stud, Kildangan
.

Notable plantings in Australia include the

Healesville, Victoria.[37] Some very large specimens survive in New Zealand, notably in Auckland where it is considered "the finest of all the elms" in that city. The 16 trees planted in 1922 around the rotunda at Auckland Zoo were described as "magnificent... with stately crowns and spreading, drooping branches".[38][39]

'Vegeta'-like cultivars

F1 hybrids between Wych and Field Elm (e.g. Huntingdon Elm) are fully fertile, but produce widely variant progeny.[40] An elm at Magdalen College, Oxford, long believed to be a wych elm, then identified by Elwes as a 'Vegeta'-type hybrid, was for a time the largest elm known in Britain before it was blown down in 1911 (see under U. × hollandica). An old 'Vegeta'-type hybrid (girth 4.5 m) stands (2017) at the University College sports ground, Abingdon Road, Oxford.[41] Bean noted that hybrids similar to Huntingdon occur naturally in parts of east-central England and may have been raised by nurseries and distributed, and that the raising and distributing of cultivars from the seed of Huntingdon will have produced elms similar to, but not the true Huntingdon clone.[16]

A mature weeping elm survives (2010) near Actons Farm in the vicinity of the Rivers Nursery,

oblong in shape, and often either revolute or convolute. The proximity of the Actons tree to the Rivers Nursery would seem more than coincidence, as the nursery was known to have sold seedlings, rather than clones, of the Huntingdon Elm, a practice which resulted in a lawsuit brought by a disgruntled nurseryman at the Oxford Assizes in 1847.[42] Elwes noted that in Hertfordshire and along the western borders of Essex "the most graceful form of this tree [weeping elm] may be seen in perfection", but he identified it as Ulmus nitens (Ulmus minor).[3]

The weeping elm once grown at

'Wentworthii Pendula' was identified by Melville
as U. × vegeta, though its leaf and form differ from those of Huntingdon Elm.
