Mûrier commun
Rubus fruticosus
La célèbre ronce d'Europe, un arbuste épineux, caduc et vigoureux à cannes arquées qui forme des fourrés denses et porte des grappes de grosses mûres noires agrégées sucrées en milieu à fin d'été. Rubus fruticosus n'est pas une seule plante, mais un AGRÉGAT de nombreuses microespèces étroitement apparentées, cultivé de longue date pour son fruit. MISE EN GARDE HONNÊTE : bien que les mûres soient comestibles et excellentes, l'agrégat de la ronce d'Europe est une INVASIVE de poids dans de nombreuses régions tempérées. Elle et la ronce de l'Himalaya étroitement apparentée (Rubus armeniacus) s'échappent des jardins en formant des fourrés épineux denses et impénétrables qui étouffent la végétation indigène, et sont de graves mauvaises herbes nuisibles dans le Nord-Ouest du Pacifique et ailleurs. Là où elle est invasive, plantez plutôt une ronce indigène adaptée à la région (Plotwright propose le mûrier des Alleghanies indigène, Rubus allegheniensis) ou un cultivar cultivé stérile ou sans épines.

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.
