Ulmus × hollandica 'Tricolor'
|Ulmus × hollandica cultivar|
|Hybrid parentage||U. glabra × U. minor|
The hybrid elm cultivar Ulmus × hollandica 'Tricolor' was first listed as U. suberosa tricolor by C. de Vos  in Beredeneerd woordenboek der voornaamste heesters en coniferen, in Nederland gekweekt 137, 1867.
The tree was distinguished by its silver-variegated foliage, the leaves near the tips of growing branches coloured red; it was not a rapid grower, however.
Three specimens were supplied by the Späth nursery to the Royal Botanic Garden Edinburgh in 1902 as U. montana tricolor, and may survive in Edinburgh as it was the practice of the Garden to distribute trees about the city (viz. the Wentworth Elm); the current list of Living Accessions held in the Garden per se does not list the plant. Beyond western Europe, the tree was known to have been marketed (as U. montana 'Tricolor') in Poland in the 19th century by the Ulrich nursery, Warsaw, and may still survive in Eastern Europe; it is not known to have been introduced to North America or Australasia.
