How do you grow the Queensland Arrowroot?
Posted by Suttons Staff on 18 December 2014 10:28 AM

The seeds of the Queensland Arrowroot also known as the Canna lily are sown from mid January through to the end of March. Soak the seeds in hot water, not boiling, in an airing cupboard for 24 hours, or until swollen, changing the water daily if necessary. Sow the seeds in small pots and place them on a windowsill or in a propagator at a temperature of 20-25º (68-70º) which should be maintained in the early stages of growth. 

In early June when the plants are about 7.5cm (3″) in height and once the danger of frost has passed they can be planted outdoors in a well drained soil that has had plenty of organic matter such as garden compost incorporated. Choose a sunny, sheltered position, spacing the plants 45cm (18″) apart. Keep the plants well watered and feed regularly with a balanced liquid fertilizer.

Harvest the rhizomes in October/November once the first frosts have blackened the foliage. The Queensland Arrowroot can be baked, boiled, mashed, roasted or stewed.
