Plant of the month – May

Canna ‘Tropicanna

The ‘Tropicanna’ Cannas is by far the most exotic when compared to all other cannas varieties. They stand out from the crowd boasting incredible foliage which is stripped with exotic colour, only to be outshone by the incredible flowers, they really are magnificent.

Planted by professionals for their impact in borders and large pots, these plants take centre stage! Cannas ‘Tropicanna’ thrive with minimal effort, making them the ideal choice for both novice gardeners and professionals alike.

‘Tropicanna’ has stunning tones of green, gold, red and black in strips over the foliage offering a fabulous backdrop for the fiery orange flowers edged in yellow.

Plant them towards the back of the border where they will rise above the smaller plants. A great option is to make them the main focus of large patio pots filled with bright bedding plants. Cannas also thrive planted close to ponds and water features, for a tropical plant, they really are incredibly versatile and worthy of Plant of The Month status!

Top Tips

Hold off cutting off old flowers – new flowering shoots come up within the dead flower and, a month or so later, will produce more flowers.

Purple and striped varieties will fade in the sun so provide shade to retain their colours.

Care Information

Water freely in dry spells.

Apply a general-purpose liquid feed in midsummer.

Little pruning or training is needed, just stake clumps in exposed positions.

When a flower spike has no more buds, prune it down to the next side shoot where a secondary flower spike should develop.

If temperatures are maintained above 10°C (50°F) cannas will remain in growth all winter and flower occasionally.

Lift the plants in autumn after the foliage has been frosted. Break large clumps into two or three and pot the pieces into 10in (or so) pots. You can then overwinter them in any frost-free shed or greenhouse, keeping them just slightly moist.

When the plants start to push up their red shoots in spring, bring them into a light place, water well and protect them from late frosts.

By June, growth will be well under way and they can be planted out once more.
