Description
Introduced in the early 1860s this finely cut leaf tree won the Award of Garden Merit in 2002 to back up its Award of Merit in 1973.
I have seen it used both in Leicester and Liverpool as a very effective street tree but it is usually best seen planted on damp soils in parkland or gardens.
The leaves are more densely cut than Alnus glutinosa Laciniata to create a uniquely fluffy and soft foliage effect that is unrivalled by other trees in the UK.
It is wonderful when planted in groups to accentuate the effect but strangely it is little used. However once seen never forgotten and I am convinced that its popularity will grow over the coming years.
