Alnus glutinosa 'Imperialis'

Slow growing and unusual, slender small tree with filigree-like, deeply cut, sea-green leaves a little similar in appearance to those of a maple. The leaves are exceptionally pretty and elegant and once established this Alder has an attractive, vaguely oriental appearance.

Alnus glutinosa 'Imperialis'   is a classic plant for damp sites and particularly ornamental when planted next to a pond or stream!

• Notes: A specimen of Alnus glutinosa 'Imperialis', planted in the arboretum surrounding our nursery reached a height of 3.5 m, a spread of 2 m after 12 years. In our experience, this selection is more slow growing than other Alnus listed here and is therefore a better choice for small gardens.
