Marjolaine des jardins
Origanum majorana
Une plante aromatique culinaire méditerranéenne tendre — un petit sous-arbrisseau touffu aux tiges carrées rougeâtres et aux feuilles rondes, gris-vertes et aromatiques, formant une touffe dressée de 1 à 2 feet. De minuscules fleurs blanc crème à rose pâle s'ouvrent à partir d'amas de bourgeons en forme de nœuds en été, d'où vient l'autre nom de « marjolaine nouée ». Rustique uniquement dans les zones USDA 9-10 ; partout plus froid, elle est cultivée comme annuelle de saison chaude ou comme plante aromatique en pot rentrée avant le gel.

Plotwright
Projected zone for this same location in 2050 (2041-2070) using SSP3-7.0 (regional rivalry).
Won't grow here
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 and still out of range 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.
