Céleri
Apium graveolens var. dulce
Un légume bisannuel de saison fraîche de la famille des carottes (Apiaceae), cultivé comme annuelle pour ses pétioles nervurés, croquants et comestibles. Apium graveolens est originaire des régions tempérées méditerranéennes d'Europe, d'Asie et d'Afrique — pas d'Amérique du Nord. Il exige un sol riche, constamment humide, et des températures fraîches et stables (60-75°F) ; la chaleur et la sécheresse rendent les tiges filandreuses et amères, ce qui en fait l'un des légumes potagers les plus capricieux.

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.

Zone 7a
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.
⚠→✕
Marginal today, but likely out of range by 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.
