Description: Alnus glutinosa ‘Imperialis’ also known as the Cut Leaved Alder, makes the most attractive and graceful selection of Alnus. Deep, fine cut leaves gives the tree a slightly oriental appearance. Purple male catkins appear during the spring followed by false cones, which are very popular with the birds! Stunning yellow autumn colours. Has many uses for making clogs, boats, building materials, gun powder charcoal, poles for fencing (also used for the underpinning of Venice), tanning and pigments of hides and for the treatment of malaria and rheumatism.
History: Introduced in 1859. Received an Award of Garden Merit from the Royal Horticultural Society in 1973.
Alnus Growing Tips: Will tolerate almost any soil condition except shallow chalk. Fast and easy to grow, thriving even in waterlogged soil. Excellent for shelter belts. Respond well to coppicing and heavy pruning at any stage. Should be encouraged as shelter trees on poorland as they are effective nitrogen fixers for other symbiotic plant life.
Height and Spread (after 10 years) : 6m x 4m
