Mock Orange

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.

Mock Orange is an ornamental shrub known for its fragrant, white flowers. The scent is often described as orange-like with a hint of jasmine. Attractive to pollinators, hummingbirds, and humans alike.

Mock Orange is highly versatile, and can be used as an ornamental shrub, either alone or as a hedge. It is well suited for streambank stabilization and riparian zone restoration, due to its ability to grow in low, moist areas as well as those that are high and dry. Lewis Mock Orange also has the capability of being used in soil bioengineering projects such as live staking.
