Water Arum

The Royal Star Magnolia, or Star Magnolia, is an early-blooming, white fragrant flower. It has a form that resembles a starburst, hence the name. This multi-stemmed deciduous shrub is extremely popular and has won the prestigious Award of Garden Merit from the Royal Horticultural Society.

The Royal Star Magnolia attracts birds and butterflies to your garden, with their large, showy flowers blooming even before it’s foliage which features a medium green leaf. They prefer slightly acidic soils.

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.
