Levisticum officinale
Une herbe culinaire vivace herbacée grande et quelque peu imposante, cultivée pour la saveur de céleri de ses feuilles, tiges, racines et graines. Originaire du pourtour méditerranéen oriental et pouvant atteindre jusqu'à 6 feet de hauteur, elle porte de petits ombelles de minuscules fleurs vert-jaunâtre au printemps au-dessus de feuilles ternées composées, profondément divisées, vert foncé, qui ressemblent à du persil aplati ou à du céleri (Missouri Botanical Garden PlantFinder).

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.
