Rosier rugueux
Rosa rugosa
Un rosier botanique robuste, exceptionnellement tolérant au sel et au froid, formant un fourré dense et drageonnant de tiges dressées et très épineuses, garnies de feuilles vert foncé profondément gaufrées (rugueuses). De la fin du printemps et tout l'été, il porte de grandes fleurs simples et parfumées, magenta-rose à blanc, suivies de gros cynorrhodons rouges en forme de tomate, comestibles et très riches en vitamine C. NC State Extension le recense pour les zones USDA 2a-7b. Sa robustesse est aussi son défaut : il se propage agressivement par drageons et par les cynorrhodons porteurs de graines, et il est envahissant sur les dunes côtières dans certaines régions du nord-est des États-Unis et du nord de l'Europe.

Les gros cynorrhodons rouges sont comestibles et très riches en vitamine C, traditionnellement transformés en gelée, sirop et thé, et les pétales parfumés servent aussi en tisanes et confitures.
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.
