Gainier de Chine
Cercis chinensis
Un grand arbuste ou petit arbre caduc à troncs multiples, originaire du centre de la Chine, cultivé pour sa dense floraison de début de printemps aux fleurs rose pourpré de la famille des légumineuses qui s'épanouissent directement sur les branches et les troncs nus avant le déploiement des feuilles. Les feuilles luisantes, arrondies et en forme de cœur suivent, et des gousses plates semblables à des haricots mûrissent et persistent jusqu'en hiver. Plus arbustif et plus densément ramifié que le gainier de l'est nord-américain, il constitue un point focal printanier compact pour les zones 6 à 9.

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.
