Correhuela mayor

Convolvulus arvensis
La correhuela mayor es una enredadera perenne baja, trepadora y de raíces profundas de la familia de las campanillas, con hojas en forma de flecha y bonitas flores acampanadas que se abren de blanco a rosa suave. No te dejes seducir: Plotwright la incluye como una entrada para conocer al enemigo, no como una planta para cultivar. Convolvulus arvensis es una de las malezas más difíciles de erradicar del mundo. Una sola planta forma un sistema perenne de raíces y rizomas que puede superar los 20 pies de profundidad, se regenera a partir del fragmento roto más pequeño y produce un banco de semillas en el suelo que sigue siendo viable durante décadas. Trepa y estrangula cultivos, perennes y arbustos, subiendo por cualquier cosa que toque. Está catalogada como maleza nociva en muchos estados de EE. UU. Aprende a reconocerla, no la plantes nunca y trata cualquier rodal como un problema de control a largo plazo. Su única virtud honesta es que las flores son una fuente temprana y duradera de néctar para algunas abejas.
Climate fit: moderate (69/100)

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.
