Mahonia rampant
Mahonia repens
Un arbuste persistant bas et rampant des montagnes Rocheuses de l'Ouest (aussi appelé mahonia rampant à raisin d'Oregon ; NC State le classe sous le synonyme Berberis repens). Il s'étend par des tiges souterraines pour former un tapis au feuillage de type houx de 12-24 inches de haut, avec un feuillage penné composé vert bleuté qui vire au bronze puis au rouge pourpre en hiver, des grappes de fleurs jaunes parfumées au printemps et des baies glauques noir bleuté semblables à des raisins en été. Robuste, très rustique, et tolérant à l'ombre et à la sécheresse une fois établi — l'un des meilleurs couvre-sols persistants indigènes pour l'ombre sèche.

Les grappes de fleurs jaunes parfumées s'ouvrent au début du printemps et sont visitées par les abeilles indigènes à émergence précoce ; une source importante de nectar et de pollen en début de saison.
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.

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.
