Production Requirements

Climate

Temperate to subtropical

Cultivation

Arrowhead is a bog or water-edge plant so it can grow in shallow water or in mud at the water’s edge.
Plant from corms or divisions in Spring in full sun. Plant about 5cm deep and at least 10cm apart to give the plants room to spread out and produce corms.
A pond
 or dam isn’t necessary to grow aquatic plants.
Arrowhead can be grown successfully in containers such as recycled concrete troughs, baths or plastic tubs. Fill the container with a 50:50 soil and well-aged manure or compost mix. Leave about 20cm headroom from the top of the container so the soil can always be covered with shallow water. Arrowhead can also be grown in wide shallow pots submerged in ponds. Place bricks under the pots to raise them up to the correct depth and mulch with a layer of gravel to keep the soil in place.

Edible parts

Corms (cooked) and young raw leaves and shoots.

Risks and weed potential

It does not set viable seed and is not considered invasive, but do not grow near waterways

Harvesting & Processing

Harvest

Harvest when the leaves turn brown. Must be harvested, thinned and re-potted annually to maintain corm size.
