Agracejo japonés

Berberis thunbergii
Un arbusto caducifolio denso, en forma de montículo y redondeado, originario de Japón, de 3-6 feet de altura y 4-7 feet de anchura, con tallos espinosos arqueados, hojas pequeñas en forma de cuchara (verdes, o de color burdeos y dorado en los cultivares), flores amarillo pálido en primavera y bayas de un rojo intenso que persisten hasta el invierno. Es resistente, repele a los ciervos y tolera la sombra, la sequía y los suelos pobres. Esa misma resistencia es justamente el problema: Berberis thunbergii es una invasora agresiva en el este y el medio oeste de los Estados Unidos — las aves dispersan sus semillas hacia los bosques, donde forma densos matorrales espinosos que desplazan a las plantas nativas. Se ha documentado que sus poblaciones elevan la humedad a nivel del suelo y albergan densidades notablemente mayores de garrapatas de patas negras (garrapatas del ciervo), el vector de la enfermedad de Lyme. Su venta está prohibida o restringida en varios estados, y casi en cualquier lugar donde sea resistente los arbustos nativos o no invasores son la mejor opción.

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
USDA
Published baseline for this location from 1991-2020.

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.
