Cala
Zantedeschia aethiopica
Una perenne rizomatosa de porte audaz, en mata, cultivada por sus elegantes flores blancas y puras en forma de embudo —en realidad una espata curvada que envuelve un espádice amarillo en forma de dedo— sostenidas en tallos altos por encima de grandes hojas brillantes, en forma de flecha y de un verde profundo, desde finales del invierno hasta el verano. Nativa de los humedales y manantiales del sur de África, Zantedeschia aethiopica es la cala clásica de floristería y una llamativa planta de borde de agua y de contenedor, que prospera en suelo rico, constantemente húmedo a encharcado, a pleno sol o media sombra. Es tierna (rústica en las zonas 8a-10b), donde pasa el invierno en el suelo y puede ser casi perennifolia; en climas más fríos se cultiva a partir de rizomas desenterrados o bajo un acolchado abundante. Dos advertencias son fundamentales: todas sus partes son tóxicas si se ingieren (rafidios de oxalato de calcio) y, en climas suaves y húmedos, puede escaparse y naturalizarse hasta convertirse en una maleza invasora.

Se cultiva estrictamente como planta ornamental y flor de corte, nunca para alimento: todas las partes de Zantedeschia aethiopica —hojas, tallos, la espata y el espádice, las bayas y los rizomas— contienen cristales insolubles de oxalato de calcio (rafidios) y son tóxicas.
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.
