Agave de Parry
Agave parryi
Un succulent à feuillage persistant en rosette, originaire des prairies, des garrigues désertiques et des forêts de piñon-genévrier d'Arizona, du Nouveau-Mexique, du Texas et du nord du Mexique entre 4 000 et 8 000 pieds d'altitude. D'épaisses feuilles rigides bleu-gris à marges dentées et pointe terminale d'un pouce forment une rosette basale dense et symétrique d'environ 2 feet de hauteur sur 3 feet de largeur. Étonnamment rustique pour un succulent — fiablement rustique jusqu'en zone USDA 7 et signalé comme survivant à -20F à condition que le froid soit sec et non humide. Chaque rosette ne fleurit qu'une seule fois, après 10 à 30 ans, en émettant une unique hampe florale de 20 feet avant de mourir, laissant ses rejets enracinés.

Zone 7a
Plotwright
Projected zone for this same location in 2050 (2041-2070) using SSP3-7.0 (regional rivalry).
Marginal
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, but marginally possible by 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.
