Latin Name:  Calla palustris
Common Name:  Water arum
Family:  Araceae
Author:  L.

Known Hazards:  The plant contains calcium oxylate crystals[222]. These cause an extremely unpleasant sensation similar to needles being stuck into the mouth and tongue if they are eaten, but they are easily neutralized by thoroughly drying or cooking the plant or by steeping it in water[65].

Mature Height:  0.25   Mature Width:  0.3

Habitat:  Forest swamps, moorland marshes, by ponds and streams[10].

Propagation Notes: Seed - best sown as soon as it is ripe in late summer in a cold frame in pots standing in about 3cm of water[200]. Sow stored seed as early as possible in the year in a greenhouse. The germination rate of stored seed is often poor. When large enough to handle, prick the seedlings out into individual pots and grow them on in trays of water in the greenhouse for at least their first winter, planting them out into their permanent positions in late spring or early summer, after the last expected frosts. Division in spring[200]. Very easy, it is possible to divide this plant at almost any time in the growing season. Any part of the stem, if placed in water or a pot of very wet soil, will quickly root away to form a new plant. Stem cuttings in summer, rooted in wet mud[200].
