Laurier-rose
Nerium oleander
Un arbuste méditerranéen robuste à feuillage persistant large, cultivé dans tout le sud chaud des États-Unis pour sa longue saison de fleurs spectaculaires — roses, blanches, rouges ou saumon — de la fin du printemps à l'automne, et pour sa tolérance quasi indestructible à la chaleur, à la sécheresse, au sel et à la réverbération du revêtement. Il forme un arbuste cespiteux, dressé et arrondi à tiges multiples qui atteint couramment 6-12 feet de hauteur (et peut être conduit bien plus haut), avec des feuilles étroites, coriaces et d'un vert profond. Le revers est grave : toutes les parties de la plante sont hautement toxiques — l'ingestion de quantités même faibles peut être mortelle pour les personnes, les animaux de compagnie et le bétail, et la fumée des tailles brûlées est dangereuse — c'est donc un ornemental strictement à regarder et jamais à toucher.

Strictement ornemental et jamais destiné à un quelconque usage humain ou animal : toutes les parties de Nerium oleander — feuilles, tiges, fleurs, sève, graines et racines — contiennent des glycosides cardiaques (oléandrine et composés apparentés) et sont hautement toxiques.
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 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.
