Prunier de mer

Prunus maritima
Un arbuste côtier bas, à ramification dense, des dunes du nord-est de l'Atlantique, couvert de fleurs blanches printanières et prisé pour les prunes bleu-pourpre acidulées qui s'ensuivent. Le Lady Bird Johnson Wildflower Center le documente comme indigène depuis le Nouveau-Brunswick jusqu'au New Jersey en descendant la côte atlantique, poussant dans les sables et graviers en bord de mer, où il est à la fois tolérant au sel et à la sécheresse. Il présente une Valeur particulière pour les abeilles indigènes, nourrit les oiseaux avec ses fruits, et est auto-incompatible — il faut un deuxième plant issu de semis pour obtenir une vraie récolte.

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.
