River Alder vs Slough Grass

Alnus incana

Beckmannia syzigachne

River Alder
Slough Grass

River Alder is a large shrub or small tree with a multi-stemmed, spreading habit. A shrub native to the boreal forests across North America, River Alder is an excellent tree for soil stabilization near rivers and creeks.

This tree is recognizable by its small brown seed cones and smooth, silver-grey bark with white horizontal lenticels. Unlike Green Alder, River Alder's seed pods are long and hang off short branches.

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

Slough Grass is a hardy grass that will happily grow in any wet soil. It is usually found near water and is common haymaking material or forage.

Slough Grass is also useful for erosion control and land reclamation.
