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.


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.


  • 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.


In this gardening tutorial, our resident gardening expert Jeff demonstrates the best way to plant Canna corms into pots to achieve an amazing display of colour in the summer.


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.

    1. Hi Terry,

      I don’t believe so. Some cannas seem able to shrug it off, but it has the potential to spread quickly from plant to plant, so it’s best to remove and dispose of affected individuals at the first sign of trouble.

  1. Brilliant instructions and a lovely photograph. Cannas are so vibrant and beautiful, they definitely make you feel as if you are on a tropical holiday!

    1. Thank you for your lovely comment! They are beautiful exotic plants for the garden to make a little tropical getaway right at home! 🙂

  2. This is nicely detailed and practical, thanks. I appreciate the way you cover points succinctly. It’s great info and I find you worth following.

  3. So sad that my tropicana cannas did not grow.
    Rhizomes were very dry when delivered. I followed all instructions,
    maybe I overwatered them, but nothing grew !
    I dug up rhizomes ,no sign of any growth whatsoever.
    This has put me off trying again.

    1. Hi Rosemary,

      Sorry to hear that you’ve had a difficult time with Cannas, maybe these tips might help bring you back in to the spirit of planting them.

      Plant them in a location where the soil drains well. If there are still water puddles 5-6 hours after a hard rain, scout out another site. Or amend the soil with the addition of organic material to raise the level 2″-3″ to improve the drainage. Peat moss, compost, ground bark or decomposed manure all work well and are widely available. Cannas thrive in soils too moist for many plants but will not survive in soggy settings. Water your cannas enough to keep the soil slightly damp but not enough for it to be soggy.
