Achira
Canna indica
Una perenne rizomatosa de aspecto tropical y porte audaz, cultivada por sus grandes hojas en forma de remo parecidas a las del banano y por sus espigas esbeltas de flores rojas, naranjas o amarillas desde el verano hasta las heladas. Nativa de Centroamérica, Sudamérica y las Antillas, Canna indica es el ancestro silvestre de muchos híbridos de canna de jardín — de flores más estrechas y porte más erguido que los vistosos cultivares modernos, con semillas negras, duras y redondas que antaño se usaban como perdigones, de donde viene su nombre común. Prospera con el calor, la humedad y un suelo rico, constantemente húmedo a encharcado, a pleno sol, donde forma matas erguidas que aportan estructura tropical inmediata. Dentro de su rango de rusticidad (zonas 8a-11b) pasa el invierno en el suelo; en climas más fríos se desentierran y se guardan los rizomas.

Más allá de lo ornamental, Canna indica es una auténtica planta alimenticia: sus rizomas almidonados (conocidos como achira o arrurruz de Queensland) se han cocinado y comido durante mucho tiempo, o se han procesado para obtener almidón, en partes de América, y también se usan los brotes tiernos y las semillas inmaduras.
Cold hardiness
Future
These values are location-based: this location's current hardiness is the baseline, and the 2050 value is a projected future climate for this same location.

Plotwright
Projected zone for this same location in 2050 (2041-2070) using SSP3-7.0 (regional rivalry).
Won't grow here
In plain terms: This location is in Zone 6b today. Its hardiness profile is cold winters, and coldest nights are typically around -3°F. By 2050, the projected hardiness zone is Zone 7a based on SSP3-7.0 (regional rivalry). That is a +0.5-zone shift from Zone 6b to Zone 7a by 2050.
✕
Out of range today and still out of range in 2050.
Heat tolerance
Future
Heat tolerance values are location-based too: heat days today are observed at this site, and the 2050 value projects this same location under a future climate.
