Pommier couronne

Pommier couronne

Malus coronaria
Un petit pommier sauvage indigène de l'est de l'Amérique du Nord, au tronc souvent tortueux, cultivé pour ses fleurs parfumées de mai — des corymbes de 2 à 6 fleurs s'ouvrant roses et pâlissant au blanc. Les petites pommes jaune-vert et acides qui suivent sont trop astringentes pour être mangées fraîches, mais font d'excellentes confitures et cidres, et nourrissent les oiseaux et les mammifères jusqu'en automne. Les fourrés épineux de ce pommier offrent abri et sites de nidification ; l'espèce est très sensible à la rouille gymnosporange et doit être tenue à bonne distance du genévrier de Virginie.

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.
Now
Zone 6b
USDA
Published baseline for this location from 1991-2020.

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.
