Water Arum

Pearly Everlasting is a native perennial wildflower known for its clusters of white, papery flowers with yellow centres. These long-lasting blooms appear throughout summer, and the silver-grey foliage adds contrast to the landscape. Its nectar supports a variety of pollinators and serves as a host plant for painted lady caterpillars.

Pearly Everlasting is also used in dried flower arrangements. It is well-suited for pollinator gardens, naturalization, ecological restoration, and low-maintenance landscapes.

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.
