WATER ARUM, WILD CALLA
- Unit price
- / per
Calla palustris is also known as bog arum, marsh calla, wild calla, squaw claw, and water-arum. It is a rhizomatous herbaceous perennial plant growing in bogs and ponds. The leaves are rounded to heart-shaped. The greenish-yellow flowers are enclosed in a white spathe. The fruit is a cluster of red berries, each berry containing several seeds.
It is native to cool temperate regions of the Northern Hemisphere including North America (Alaska, Canada, and northeastern contiguous United States), Europe (France and Norway eastward), and Asia.
Type: Hardy perennial water plant
Hardiness zones: 4-9
Height: 18", 45cm
Location: Sun or shade
Seeds per packet: 15
Your planting container should be waterproof, and not have holes at the bottom. Fill the container with good soil. Sow the seeds just under the surface, and then fill the tray with water to the top of the soil. Leave them at room temperature for 3-4 weeks. This helps break the phytohormones which inhibit germination. They will not grow yet. Then a cooling period is required. Cover them with plastic and place in a fridge for 4-6 weeks. Be sure they stay wet. After the cold stratification period they are then brought back to 21C, 70F for them to germinate. Germination is generally 30-60 days after the warming period, though some can take longer.
Ornamental use only. These seeds and/or plants are poisonous.
