In the garden

A member of the Cannaceae grown for its long display of summer-to-autumn flowers, Canna 'America' is used where bold, architectural planting is required without exotic care routines. As a perennial, it establishes as a clump that flowers from July to October and is commonly included in borders, containers and tropical-themed plantings. Plant in a sunny, sheltered position with rich, well-drained soil that retains moisture; avoid waterlogged sites. Regular watering through the growing season helps maintain vigour, especially in containers where the root run is limited. Feed with a balanced fertiliser during spring and summer to support sustained flowering, and apply a mulch to conserve moisture and moderate soil temperature. Canna 'America' carries an H4 (average) hardiness rating, which means it will suit much of the UK with some winter protection in colder or exposed gardens. It works well at the back of perennial borders, as a feature in a large patio pot, or within a tropical-themed bed where its extended July–October bloom helps bridge late summer into autumn and keeps containers and borders active into the cooler months.
