Limelight Hydrangea vs Water Arum

Limelight Hydrangea is a flowering shrub that is known for its green flowers. As they mature, the flower colour changes from a pale green to a creamy white, followed by shades of pink and red. Hydrangea flowers persist longer compared to other flowering shrubs, blooming from late July into fall. They are a popular choice for flower arrangements.

The Limelight Hydrangea can be grown as a stand alone shrub, as a hedge, or incorporated into a flower garden. Blooms occur on new wood, so regular pruning is encouraged in late winter. This is an award winner from the Proven Winners® collection.

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.
