Alnus glutinosa Imperialis is a finely cut-leaved version of the common Alder, Alnus glutinosa which won the Award of Garden Merit in 2002. This beautiful tree has delightfully well cut leaves, given them an almost fluffy appearance, with the bright green colour of the foliage contrasting well against the blue sky during the summer months.
There are very few trees seen in the UK that have such densely cut, soft look to them. Despite giving a highly ornamental look, being part of the Alder family, Alnus glutinosa Imperialis is actually well suited to wet and damp soils. It is therefore an interesting choice for this use compared to some of the more common offerings of Poplar and Willow.
It is little planted in the UK; however we consider that it is a tree whose popularity will increase with time and exposure in the landscape. Like other Alder, Alnus glutinosa Imperialis will tolerate most soil conditions, including moist soils.
Take care not to plant in exposed areas as the delicate foliage can be damaged by the wind. If planted as a single specimen, this tree will produce a magnificent pyramidal shape.
This small Cut Leave Alder is wonderful planted in groups to accentuate the effects of the light and fluffy green foliage.
Mature height: 12-17m
