The Sapporo Autumn Gold Elm tree, is a hybrid Elm with an upright, light canopy. It is suitable for a medium sized garden.
Sapporo Autumn Gold Elm trees can reach a height of about 15 metres.
How Standard Trees are Measured:
All the plants in the ornamental trees section are graded as standards, which means that they are measured by their girth in centimetres 1 metre above ground level (basically, their trunk's waist measurement). They aren't measured by their height, which will vary. So, a 6/8 standard has a trunk with a circumference of 6-8 centimetres and an 8/10 standard has a trunk 8-10 centimetres around. This measurement makes no difference to the tree's final height.
Standard trees are 2 - 3.5 metres tall (on average) when they arrive; they are the most mature trees that you can buy from us. We cannot tell you precisely how tall your trees will be before we deliver them.
General description of Sapporo Autumn Gold Elm trees:
This is a medium sized, upright and spreading tree with an open canopy that does not cast very dense shade, making it a good choice for the average sized garden. The shiny leaves are narrow, serrated ovals which, true to their name, turn a warming yellow in autumn before they fall. The lemon and lime coloured spring foliage is attractive too and sometimes carries a hint of pink.
Ulmus Sapporo Autumn Gold is a fine tree in its own right, but to call it an Elm might be misleading to some people, as it doesn't look anything like the grand old Elms that have now all but vanished from Britain. But as far as the White-letter Hairstreak butterfly and White spotted pinion moth are concerned, it may as well be the same tree. Both species depend on Elm leaves for their caterpillars to feed on and are just about surviving in this country. It is probably too late for native populations of the large tortoiseshell butterfly, which is also partial to Elm, but planting these trees gives them a chance of staging a comeback from captive specimens.
History & uses of Ulmus Sapporo Autumn Gold:
This tree was cultivated by Dr Eugene Smalley of the Wisconsin University in the late 1950's, with seeds from the botanic gardens at Hokkaido university in Sapporo, Japan. It is a hybrid of Japanese Elm and the dwarf Siberian Elm, Ulmus pumilia, and is highly resistant to Dutch Elm Disease, though not immune to it.
