Royal Alder (Alnus Glutinosa Imperialis)

Royal Alder (Alnus Glutinosa Imperialis) is an ideal choice of an unusual tree for a wet site. It is a cut-leaved form of the common alder, and it has all the advantages of that robust species. Soil that is saturated for part of each year suits it very well. The nitrogen fixing nodules found on the roots of the species also occur on the roots of the cultivar, so it can live in very poor conditions. This is a light green summer foliage feature. Its leaves are deeply cut giving a lacy or even misty look especially when it is planted beside water. The best results are achieved where it is used in mixture with other trees and shrubs. Royal Alder (Alnus Glutinosa Imperialis) is the arborial equivalent of the Gypsophila in a bouquet of roses. Royal alder was first cultivated in 1859, probably as a selection of 'Laciniata', a stronger growing cut-leaved alder selected in France before 1819. Like most ornamental trees, Cut Leaved Alder trees do not require much pruning once they have established. Simply remove any crossing, damaged or diseased branches. Prune in late winter or the early spring. If you think the canopy is overcrowded, make sure to alleviate the branches to ensure enough air and light can penetrate. Alder trees produce their own nitrogen so they do not require fertiliser, only a consistently moist soil. For more Alder trees click here
