Grey Alder

Korean Boxwood is a vibrant evergreen shrub. A top choice for colder climates, this shrub will look stunning lining a driveway or as a foundation plant.

Easy to root in and maintain, Korean Boxwood's thick foliage is deer resistant and turns an attractive yellow-brown to purplish in winter. Consider applying mulch around the base to keep the roots moist and cool.

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.
