Fuchsia de Californie
Epilobium canum
Un sous-arbrisseau natif de l'Ouest nord-américain, résistant à la sécheresse (longtemps connu sous le nom de Zauschneria), qui illumine les terrains secs et rocailleux de fleurs tubulaires écarlates du milieu de l'été jusqu'aux gelées — précisément au moment où les colibris migrateurs et résidents ont besoin d'une source de nectar en fin de saison. Des tiges fines et très ramifiées portent de petites feuilles lancéolées vert grisâtre ; la plante entière s'épanouit en plein soleil, dans un sol pauvre et avec très peu d'eau une fois établie.

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.
✕
Out of range today and still out of range 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.
