Grey Alder
Tall Manna Grass

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.

Manna Grass and other waterside plants are an excellent way to prevent erosion and provide habitat and forage for animals. The difference is that Manna Grass looks better doing it! With distinctive purple grains at the top of its stalks, Manna Grass adds a splash of color to the waterside that most other aquatics can't offer.

Manna Grass is good for returning disturbed sites to nature and provides nourishment to many animals, except for cattle who find it toxic.
