Variegated Dogwood
Water Arum

Variegated Dogwood is a small shrub that is often used in the first row of a shelterbelt, as a hedge, or for soil stabilization projects. It has the same distinctive red bark, white flowers, and berries as Red Osier Dogwood.

The key difference between the two is the leaves. Where Red Osier's leaves are green throughout, Variegated Dogwood has a white outline around each leaf, giving this shrub a distinctive look.

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.
