Start rhizomes off in a greenhouse or conservatory in spring, planting outdoors after the danger of frost has passed.

Lay the root horizontally, 5cm deep in a large pot filled with potting compost and keep the soil damp.

In late May or early June, choose a sunny location with well-drained, rich soil.  Plant Cannas 10cm deep and 30-45cm apart.

From July to October, robust stems of exotic, vibrant blooms reach heights of 50-125cm depending on variety.

Shorter cultivars are suitable for pots.

Lift rhizomes in autumn or bring pots undercover for the winter months as tender Cannas do not tolerate freezing temperatures.
