This attractive marginal plant produces simple white arum-like flowers in late spring, followed by bright red berries in autumn. It has heart-shaped glossy mid-green leaves, and spreads gradually on plump, shiny, creeping stems. It thrives in shallow water, and can be used to disguise the pond's edge with its lush, slightly exotic-looking leaves. Unlike many pond plants, it will grow and even flower in shade, although planting in sun or part shade will result in more blooms. Please note that it is toxic if eaten. 

This plant is supplied bare root - it likes to grow horizontally so it is difficult to produce in mail-order-sized pots since it quickly 'jumps' them. We produce reasonable amounts as potted plants but not enough to keep up with demand. Therefore we have decided to offer it as a bare-root plant. You will receive one good rhizome with roots.

Since Calla palustris plants like to grow as a horizontal rhizome, we have recommended a 3 or 4 litre pot for your plant because these will have a wide opening. However, a 2 litre pot would be enough if it has an opening of at least 20cm. 

If designing a planting scheme, we recommend approximately 2 Calla palustris plants per square foot of ground, or 1 plant per linear foot of pond edge. Read more here on how to pot and care for your plant.
