Panicle Canna

Canna paniculata is a rhizomatous species native from southern Mexico through tropical South America. Kew records it as a geophyte of seasonally dry tropical regions, while a species profile from Brazilian landscape specialist Raul Cânovas describes its upright clumps and seasonal growth. [Kew Plants of the World Online](https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:315579-2) and [Jardim Cor](https://www.jardimcor.com/paisagismo/canna-paniculata/) treat it as a distinct species rather than a garden hybrid. ## Garden Use The large green leaves and red flowers give this species a strong vertical presence in tropical borders and larger groupings. Jardim Cor recommends planting near water or in moist soil, while cautioning against permanent inundation. Its description gives a height of 1.5–2.7 m and flowering from spring into early fall. ## Siting and Soil Provide full sun and moist but freely draining soil. The reported height converts to about 4.9–8.9 feet; the catalog's 2.4 m point lies within that range. The existing 1.2 m width corresponds closely to the catalog label of about 4 feet; keep enough room for its rhizomatous clumps. ## Maintenance Divide the rhizomes to propagate or manage a vigorous clump. In cold climates, protect rhizomes from frost and use local guidance for overwintering cannas.
