Sauge des bois
Salvia nemorosa
Vivace herbacée en touffe de la famille des lamiacées (Lamiaceae), originaire d'Europe et d'Asie centro-occidentale. NC State Extension décrit une plante dressée, à tiges multiples, d'environ 1.5-3 feet de hauteur et jusqu'à 2 feet de largeur, aux feuilles aromatiques gris-vert ridées et dentées, et aux épis denses de fleurs lavande à bleu-violet (certains cultivars roses) de juin à septembre. Elle fleurit par vagues — couper les tiges fanées jusqu'aux feuilles basales provoque une nouvelle floraison — et elle est tolérante à la sécheresse, résistante aux cerfs et lapins, et un aimant pour les abeilles, papillons et colibris. Une valeur sûre, peu exigeante, pour les bordures ensoleillées et les plantations de plantes à pollinisateurs.

Les épis floraux denses constituent une importante source de nectar : NC State Extension signale que les fleurs attirent les abeilles, les papillons et les colibris, et la taille des tiges fanées maintient des fleurs fraîches (et des visites de pollinisateurs) de juin à septembre.
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.

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.
