Grow your own Arrowroot! Canna Edulis is a beautiful decorative plant that is also edible. Shoots, immature seeds and leaves can be eaten. The rhizome (toot) can be eaten raw or cooked. It has a taste of a new potato. The best use, though, is making your own arrowroot. While there are a few plants used to make arrowroot powder, Canna Edulis is the prettiest. Just mash the roots, immerse them in water and then filter out the starch. Once dried you have your own arrowroot powder.
Requires a deep rich well-drained soil in a sunny position. Tolerates heavy soils. The plant has large leaves and dislikes windy conditions since this can tear the leaves to shreds. Requires ample water in the growing season. Tolerates a pH range from 4.5 to 8. This species should be given a good mulch if left in the ground overwinter. The top growth tolerates light frosts and plants can be grown in areas with winter snow. The tubers can be harvested in late autumn after the top growth has been killed back by frost and stored over winter. They should be kept in a frost-free place covered in moist soil or leaves. The root can be harvested within 6 months from planting out, though larger yields are obtained after 8 - 10 months. Plants are rarely troubled by pests or diseases. Slugs love the young growth in spring and can cause serious damage to plants. US Zones 7-10
Propagation Seed - pre-soak for 24 hours in warm water and sow in a warm greenhouse. Plant the seeds 2 - 5cm deep in individual pots. Scarifying the seed can speed germination, especially if the seed has not swollen after being soaked. The seed usually germinates in 3 - 9 weeks. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Division of the root clump as the plant comes into growth in the spring. Each portion must have at least one growing point. Pot up the divisions and grow them on in the greenhouse until they are well established and then plant them out in the summer.
