Description
Even if a bit exotic looking, the Water arum is a very cold hardy, rhizomatous species usually growing and forming colonies in still, shallow waters.
It flowers in May and the flowers are formed from a showy, wide white spathe, surrounding a cylindrical spadix (same like the Jack in the pulpit). It also has beautiful heart-shaped leaves growing outside of the water, and towards the fall it displays clusters with red berries.
A very hardy and reliable flowering species for wet areas in a cold climate; ponds, streams edges or even for water-containers.
The whole plant contains calcium oxalate crystals (like other Araceae) which makes it toxic to mammals. However, it was used traditionally by the Indigenous People for medicinal purposes (treating snakebites, swelling, and soreness).
Germination: sow in late fall/early winter. The seeds require +/- 3 months of cold-moist stratification; keep the seed tray constantly moist (we have to imitate the natural habitat).
