Frêne blanc
Fraxinus americana
Grand arbre indigène de la canopée de l'est de l'Amérique du Nord, le frêne blanc (Fraxinus americana) est prisé pour son bois droit, ses feuilles composées et sa coloration automnale pourpre à bordeaux fiable. HONNÊTETÉ : il ne peut plus être recommandé pour de nouvelles plantations sur la majeure partie de son aire. L'agrile du frêne (EAB, Agrilus planipennis) est une menace mortelle quasi certaine partout où il s'est répandu, tuant la quasi-totalité des frênes non traités en quelques années après l'infestation. Considérez cette fiche comme la documentation d'une espèce historiquement importante, et non comme une recommandation de plantation : ne plantez que là où l'absence d'EAB est confirmée et où vous êtes prêt à un traitement systémique à vie ; sinon, choisissez une autre essence de canopée que le frêne.

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).
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.
