Pommier
Malus domestica
Le pommier cultivé — un arbre caducifolié des Rosacées cultivé pour ses fruits comestibles décoratifs et sa floraison parfumée d'avril, composée de cinq pétales blanc à rose disposés autour d'un cercle d'étamines jaunes. Non originaire d'Amérique du Nord (le genre Malus couvre l'Europe, l'Asie et l'Amérique du Nord, mais le pommier cultivé est une lignée hybride de l'Ancien Monde). Presque toutes les variétés sont auto-incompatibles : un second cultivar de pommier différent, fleurissant au même moment, doit être à proximité pour que le fruit se forme, et les arbres sont cultivés sur porte-greffes nains, semi-nains ou de taille standard qui déterminent la taille finale.

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.
