Description and Growing Information

ShapeNarrow
LandscapeUse this canna to create an undeniably tropical look, evoking a feeling of orchids and halaconia even where there's frost. Add to existing beds and borders for dramatic, long lasting foliage contrast form or texture. A natural beside pools and water gardens. In spare modern gardens use in masses or living columns.
PropagationPropagate by division.
CultivationVery high moisture needs; do not let dry out between watering. Suitable for bogs and water gardens. Plant outside in early summer in a sheltered location in full sun. Keep soil wet in dry weather. Benefits from a monthly application of high potassium fertilizer. When frost blackens the foliage in autumn, lift the rhizomes; over winter store frost-free in barely moist peat-free soil or leaf mold. In milder conditions, leave in the ground and cover with dry mulch.
HabitatHorticultural origin.
