Persea americana
Un arbre à feuillage persistant non rustique au gel, de la famille des lauracées, originaire du Mexique et d'Amérique centrale et cultivé sous les tropiques et les subtropiques pour ses fruits crémeux en forme de poire. Des feuilles elliptiques vert foncé et brillantes de 4-8 inches habillent un arbre atteignant 30-60 feet, orné de panicules de fleurs vert jaunâtre qui donnent de grandes baies à graine unique. Rustique uniquement dans les zones USDA 10-12 — plus au nord, c'est une curiosité d'intérieur facilement obtenue depuis un noyau, mais qui fructifie rarement.

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.
