Botanical Name

CANNA 'Australia'

Plant Common Name

Australia Canna, Canna, Canna Lily

General Description

This is by far the most spectacular purple-leaved canna in the trade. The tall ‘Australia’ boasts large showy lily-like flowers of deep red, which contrast nicely with its dark purple to near black leaves.

Cannas are easy-to-grow large tropical to sub-tropical herbaceous plants. Most species originate from tropical America, but almost all cultivated varieties are hybrids. Where hardy, they are grown as perennials and in colder regions they are commonly grown as vigorous tender perennials.

The exciting ‘Australia’ features deep dark leaves and clusters of red flowers that appear from midsummer to frost but may flower nearly year around in exceptionally mild climates. Its flowers are borne atop tall upright stems and attract insect pollinators and hummingbirds.

Canna is amazingly adaptable. Plants prefer full sun and rich moist to wet soil but can be surprisingly drought tolerant if faced with a bout of dry weather. The thick fleshy rhizomes of cannas transplant and divide easily. In temperate zones, they may be dug and brought into a cool, dry garage or basement to over winter and then planted again in spring after the last frost date.

Use these in containers, waterside gardens or as focal points in any bed or border. Because cannas dwell in both wet soil and dry, they are perfect for water garden settings, though they will not tolerate deep standing water.
