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.

The Shiny Cotoneaster (Hedge Cotoneaster) is a dense, deciduous shrub that gets its name from the glossy dark green leaves that turn an eye-catching mix of red and purple in the fall.
It produces small, pink flowers in spring and by late summer they are followed by red berries that ripen to black. This plant is great for attracting wildlife as it is loved by both birds and butterflies.

While the Shiny Cotoneaster does produce berries, they are inedible to humans. This plant takes pruning and shearing well, making it easy to shape to your liking and is a great choice for a hedge or privacy screen in your yard.
