You Can Grow Colorful Cannas – Part I

Cannas are (circle all that apply) colorful, tropical, large-flowered, bold, brash, bright, sometimes gaudy, glorious, short or tall, a glorious garden plant.   I hope you circled them all, because cannas are all of the above.    Plus very delightful and very variable.

If you have an entirely desert landscape, cannas won’t look right in your landscape. But – if you are like most of us in the Southwest – you have an oasis zone in your low-water landscape (we used to call ’em xeriscapes), thus cannas will fit right in.    Cannas also grow well in a water garden.    So yes – you can grow cannas in the Southwest.

Lush Looking

The broad flat leaves of cannas are typically solid green but some cultivars have maroon, bronzy, or even enchantingly variegated (striped) leaves. Also fascinating to behold is how the leaves emerge. They grow out of a stem in a long tapering roll and once fully grown they will unfurl.

Canna Flowers

While the leaves are wonderfully striking, the flowers are stunning.    Almost like a living tiki torch, the flame colored flowers appear on a long lasting spike. Individual flowers sequentially grow in an upwards spiral in vivid hues of crimson, scarlet, golden, yellow, orange, or a sunrise blend of all of these colors.

How to Grow Colorful Cannas

Light
Here in the Southwest, cannas grow best in some afternoon shade in summer. They are used to tropical sun, not desert sun.

Water
Provide ample water.
Mine grow in pots in the water garden with the bottom half inch in the water. They have as much water as they want.

Soil
Plant in well-drained rich soil.  This means that “cactus mix” is just fine. I often say this about cactus mix because it’s about the only potting mix I use anymore. Less fussing over this blend or that. If it a plant isn’t happy in cactus mix, or in the ground – then I don’t grow it.

Containers

Cannas do well very in containers, but be sure to select the right pot for the final size of the variety you have. The large leaves can act like a sail and pot that is too small can tip over on a windy day.

Temperature
Cannas will die back to their below ground rhizomes for the winter if it gets much below 40F where you live. Don’t throw them away! Once the soil warms up they will reappear.

If you live in those colder elevations of the Southwest (USDA Zone 7 or colder) You will need to grow your cannas in pots and bring the pots to a non-freezing area for the winter. I’d say basement – but not too many of those here. A garage might work.

Do Try Some

I grow cannas for their colorful flowers, for their lush leaves, and because – in the summer at least – they help shade the fish in my water garden!
