Grey Alder
Wild Privet

River Alder is a large shrub or small tree with a multi-stemmed, spreading habit. It is an excellent tree to plant if you want to stabilize the soil near rivers and creeks.

Unlike the other alder varieties, River Alder is attractive enough to be included in riverside plantings by municipal and provincial park organizations.

Note: We use Grey Alder for Alnus incana. This species is also known by many other common names, including River Alder, Speckled Alder, and others. Please confirm the scientific name to ensure you are ordering the correct plant.

Wild Privet is a fast growing ornamental shrub that is well suited for forming hedges and privacy screens. It will retain its leaves in warmer climates but drops them in colder areas. They have small white flowers, though the smell is often considered unpleasant. While the berries are inedible, they are a good food source for many bird species.

It is recommended to prune Wild Privet immediately after flowering, as it can readily self seed. It is deer and rabbit tolerant. It can grow in dry areas, on slopes, and withstand the wind making it well suited for many growing conditions.
