They seem to grow just the same as Green Ash so I hope in the future they will planted everywhere since we really lack red colour in the fall in this city!
European Mountain Ash is a much larger tree, growing to 30 feet high or more. The leaves and berries are smaller and the fall colour is really variable compared to American Mountain Ash. This one in my neighbourhood is a favourite of mine, lots of orange-red colour in the fall, the one on my property is quite different though, it mostly turns orange-yellow in the fall, if it turns at all, sometimes the leaves are still green until a very hard frost! There are cultivars of this variety which have a smaller more unified form and more reliable colour. The berries of all varieties remain through the winter to be food for Cedar Waxwings and drop all over your patio the rest of the year!
