Silver Leaf Willow
Water Arum

Native to North America, Silver Leaf Willow has orangish bark and long, silvery grey leaves. Bees and other insects are attracted to its flowers.

Popular as an ornamental tree for parks, it is also used as a shelterbelt species. It may not be as cold hardy as some of the other willow varieties, however.

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.
