Yuca de las praderas

Yucca glauca
Una yuca resistente y siempreverde de las Grandes Llanuras que mantiene una roseta baja de hojas angostas, azul-verdosas pálidas, en forma de daga, y que en el inicio del verano lanza un tallo floral de 4 1/2 feet con flores colgantes en forma de campana, blancas verdosas. Extraordinariamente tolerante a la sequía y a los suelos pobres, depende de un mutualismo obligado con la polilla de la yuca (Pronuba) — el único insecto que la poliniza —, por lo que no produce semilla todos los años. La raíz se ha utilizado desde hace mucho tiempo para fabricar jabón, de ahí su nombre común.
Native: 13 US states + 2 CA provinces

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.
