Water Arum
Golden Lights Rhododendron (Azalea)

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.

Golden Lights Rhododendron is an exceptionally cold hardy, deciduous azalea. Part of the Northern Lights Series, this shrub was cultivated specifically to withstand harsh winters, making it ideal for our prairie climate.

In late spring you'll be drawn to its beautiful, golden, sweetly fragrant flowers. Pruning is recommended after the flowers are spent to control the size and shape of this shrub.

Consider Golden Lights Rhododendron when planning your next hedge, or plant it on its own as a striking specimen plant.
