Cannas are a fantastic addition to any summer garden. They are an excellent perennial that will add plenty of exotic style and colour to your garden displays. Their attractive dark leaf foliage with bright coloured showy flowers. They come in a range of vibrant colours from orange, red, pink and yellow which make great summer bedding as well as a part of your summer borders or patio display.

Planting

Cannas can be planted in April/May at a depth of between 7 and 10cm. They are often best started in pots and then transplanted in borders or beds towards the end of May. The best placement for them is to plant them in a sunny position, preferably out of the wind. Be sure to water during warm weather.

Tips

  • After your cannas settle in to the ground, roots and sprouts will form within a few weeks, or you can start your tubers indoors in a pot for earlier blooms as cannas need heat to keep them growing.

Aftercare

After planting, water your Cannas generously to settle the soil around the rhizomes. After blooming has finished for the season, leave the foliage in place, do not cut it off. The leaves gather sunlight and provide nourishment for next year’s blooms. Remove leaves when they begin to turn. Your Cannas will rest for a few months before beginning their next cycle of growth in the Spring.
