Water Arum
Rosy 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.

Rosy Lights Rhododendron is the next flowering, deciduous shrub you need in your garden. It is incredibly cold hardy and produces fragrant, bright pink blooms in late spring. Pruning is recommended after the flowers are finished to control the size and shape of this shrub.

Try Rosy Lights Rhododendron when planning your next hedge/screen, or plant it on its own as a striking accent plant. Part of the Northern Lights Series.
