Mûrier des Alleghanies

Rubus allegheniensis
Un arbuste indigène d'Amérique du Nord orientale et centrale, formant des fourrés, produisant des cannes arquées et épineuses ainsi que des grappes de grosses mûres noires sucrées en milieu à fin d'été. Parmi les producteurs de fruits sauvages les plus importants pour la faune dans les forêts de l'est — oiseaux, mammifères et insectes dépendent tous de ce fruit. Comme le framboisier, il a des cannes bisannuelles (primocane en première année, fructification en deuxième année en tant que floricane, puis mort). Se propage par drageons et par enracinement des extrémités de cannes ; à gérer par une taille annuelle.

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.

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.
