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.

Dwarf Arctic Willow is a beautiful ornamental shrub that attracts butterflies. It grows into a low dense, rounded shrub with slender purple stems. The Dwarf Arctic Willow has bluish-green foliage throughout the season and stunning when planted as an artistic hedge. Cold hardy and juglone tolerant, this shrub will make a nice addition to your urban garden.
