Sapin de Douglas
Pseudotsuga menziesii
Un très grand conifère du Pacifique Nord-Ouest — 12-24 m en culture mais dépassant 90 m à l'état sauvage — et l'un des arbres à bois les plus importants d'Amérique du Nord. Les bractées de cônes fourchues en forme de trident dépassant entre les écailles le distinguent de tous les autres conifères. Les aiguilles vert foncé, plates et disposées en spirale, dégagent un parfum lorsqu'on les froisse et laissent des cicatrices circulaires surélevées sur les rameaux.

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.

Zone 6b
USDA
Published baseline for this location from 1991-2020.

Zone 7a
Plotwright
Projected zone for this same location in 2050 (2041-2070) using SSP3-7.0 (regional rivalry).
Won't grow here
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.
⚠→✕
Marginal today, but likely out of range by 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.
