Pamplemousse

Citrus x paradisi
Un agrume à feuillage persistant à larges feuilles atteignant 15-30 feet de hauteur et de large, avec un feuillage brillant, des épines acérées sur ses rameaux et des fleurs blanches à quatre pétales très parfumées. Les gros fruits (plus de 3 inches de diamètre) mûrissent en jaune pâle, souvent tachés de rose, sur une chair allant du blanc crème au rouge profond selon le cultivar. Un arbre subtropical rustique seulement jusqu'à la zone USDA 9a, cultivé en plein air dans la ceinture des agrumes et comme plante en pot hivernée plus au nord.

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).
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.
