Érable du Japon

Acer palmatum
Un petit arbre ou grand arbuste caduc originaire du Japon et de Corée, cultivé avant tout pour ses délicates feuilles palmées — cinq à sept (rarement neuf) lobes pointus et dentés — et son port sculpté aux ramifications étagées. Il atteint 10-25 feet au fil des décennies, porte des fleurs insignifiantes rouge pourpré en avril, et termine la saison dans des teintes de jaune, rouge-pourpré et bronze. Un spécimen classique et un arbre de sous-bois à ombre filtrée ; non originaire d'Amérique du 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.
Now
Zone 6b

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.
