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.

Annabelle Hydrangea is a cold hardy shrub that is well known for its large, compact clusters of white flowers. Unlike other flowering species, Hydrangeas do best in partial shade. However, they are capable of growing in full sun if the soil is kept consistently moist.

Blooms occur on new wood, so regular pruning is encouraged in late winter. Try Annabelle Hydrangea as a border or on its own.
