Water Arum
Dwarf Arctic Willow

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.

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.
