Camas común

Camassia quamash
Un bulbo nativo de floración primaveral de los prados húmedos del noroeste del Pacífico y las Rocosas del norte, la camas común produce un escapo de 2-3 feet cubierto de docenas de flórulos estrellados azul-violáceos que se abren de abajo hacia arriba sobre follaje basal similar al de las gramíneas. Es la camas cuyo bulbo fue alimento básico de los pueblos indígenas de toda su área de distribución — el nombre del género proviene del vocablo nativo americano "kamas"/"quamash". Lady Bird Johnson Wildflower Center la señala como planta de especial valor para las abejas nativas.

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.
Now
Zone 6b
USDA
Published baseline for this location from 1991-2020.

Well-suited
2050
Zone 7a
Plotwright
Projected zone for this same location in 2050 (2041-2070) using SSP3-7.0 (regional rivalry).
Well-suited
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.
Well-suited today and still thriving 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.
