Water Arum

Pussy Willow is a large shrub or small tree that produces catkins that are soft, silky, and silvery before leaves appear in the spring. This native willow prefers moist to wet soil.

Pussy Willow makes a beautiful accent tree, and its bright branches can be used for floral arrangements or basket making.

All willow are important to native pollinators each spring as they have higher amounts of pollen and nectar early each growing season when other food sources are scarce.

Water Arum is a native perennial wetland plant known for its showy white oval sheaths (spathe) that surround a yellow-green, cylindrical flower spike (spadix). It has large, oblong, heart-shaped leaves on stems that rise above the water from shallow, spreading rhizomes. The blossoms are followed in late summer by tiny, pear-shaped fruits that ripen to bright red, adding ornamental interest to wet habitats.

Water Arum provides food for birds and small mammals that eat its berries, and its flowers attract pollinators. It can tolerate cold climates and forms colonies in shallow water and saturated soils. It is well-suited for ecological restoration, riparian planting, naturalisation, and habitat projects in wet and shaded environments.
