Arrowwood is a cold hardy, reliable, and vigorous shrub that can easily grow on difficult sites. Featuring an upright, rounded, and multi-stemmed form, this shrub produces creamy white flowers against a backdrop of deep green, serrated foliage.

The flowers give way to dark, blue berries that will attract wildlife to your yard. Depending on the plant, Arrowwood's striking fall color can range from yellow, red to reddish-purple.

Many use Arrowwood for naturalization or mass planting projects but, more commonly, you'll see this simple yet elegant shrub as a shrub border or planted on its own.

Red Alder is a fast-growing deciduous tree native to western North America. Its fixes nitrogen, which enriches soils and supports the growth of surrounding plants. Ideal for sites with poor soil conditions, or areas disturbed by logging, construction or fire.
It provides shade in riparian areas, creating cover for fish. Its seeds and buds are eaten by birds and small mammals, while the foliage provides browse for wildlife. The catkins release clouds of pollen attracting bees and other insects.
The Red Alder gets its namesake from the rusty-red color the bark turns when bruised.
