White Lights Rhododendron (Azalea)
Water Arum

White Lights Rhododendron is part of the Northern Lights Series, cold hardy, and deciduous. In late spring you'll be drawn to its fragrant white blooms. In fall, the foliage turns a beautiful purple-bronze color. Pruning is recommended after the flowers are spent to control the size and shape of this shrub.

White Lights Rhododendron should be your next hedge/screen, or plant it on its own as a specimen plant.

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.
