Yellow Twig Dogwood
Water Arum

Yellow Twig Dogwood is a small deciduous shrub with attractive, bright yellow bark.

It features delicate white, star-shaped flowers and white fruit. It is often used as a screen, and its wide-spreading roots help stabilize areas experiencing soil erosion.

Yellow Twig Dogwood complements Red Osier Dogwood, and it is a great filler to add winter color to shrub and flower gardens.

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.
