Muflier
Antirrhinum majus
Le muflier classique des jardins de cottage — nommé pour ses fleurs à deux lèvres articulées en « gueule de dragon » qui s'ouvrent brusquement quand on les pince sur les côtés. Une vivace de courte durée originaire du sud-ouest de l'Europe, rustique en zones USDA 7-10 mais cultivée presque partout comme annuelle de saison fraîche, portant de hauts épis de fleurs blanches, jaunes, roses, rouges, orangées, pêche ou violettes du printemps jusqu'aux gelées. Les colibris et les papillons butinent abondamment ses fleurs, et les épis coupés sont un classique des jardins à couper.

2050
Zone 7a
Plotwright
Projected zone for this same location in 2050 (2041-2070) using SSP3-7.0 (regional rivalry).
Marginal
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, but marginally possible 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.
