Western Snowberry
Grey Alder

Like the Common Snowberry, the Western Snowberry is a small shrub with pink flowers useful for feeding livestock and preventing erosion. Unlike the common species, however, the Western Snowberry is much more suited to wet conditions, capable of persevering through poor soil drainage and occasional flooding.

After the Snowberry's flowers have bloomed, it produces berries which often last on the plant through winter. These berries are toxic to humans, but livestock and local wildlife love them! Those hoping to attract wildlife to their property can plant Snowberry and expect to see animals foraging on it much later in the year than other plants.

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.
