Épine-vinette du Japon
Berberis thunbergii
Un arbuste caduc dense, en monticule et arrondi, originaire du Japon, de 3-6 feet de hauteur et 4-7 feet de largeur, aux tiges épineuses arquées, aux petites feuilles en forme de cuillère (vertes, ou bordeaux et dorées chez les cultivars), aux fleurs jaune pâle au printemps et aux baies rouge vif qui persistent jusqu'en hiver. Il est robuste, résistant aux cerfs et tolère l'ombre, la sécheresse et les sols pauvres. Cette robustesse même est justement le problème : Berberis thunbergii est une envahissante agressive dans l'est et le Midwest des États-Unis — les oiseaux disséminent ses graines dans les forêts, où elle forme des fourrés épineux denses qui supplantent les plantes indigènes. Il est documenté que ses peuplements augmentent l'humidité au niveau du sol et abritent des densités nettement plus élevées de tiques à pattes noires (tiques du cerf), le vecteur de la maladie de Lyme. Sa vente est interdite ou restreinte dans plusieurs États, et presque partout où elle est rustique, les arbustes indigènes ou non envahissants sont le meilleur choix.

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.
