Toyon

Heteromeles arbutifolia
L'arbuste à feuilles persistantes emblématique du chaparral californien et des collines côtières — feuilles vert foncé coriaces aux dents prononcées, inflorescences estivales plates de petites fleurs blanches, et les pomes rouge vif qui lui ont valu les noms de baie de Noël et houx de Californie (et, par le biais des collines d'Hollywood, prétendument le nom « Hollywood »). Longévif et profondément tolérant à la sécheresse ; les baies hivernales nourrissent plus de vingt espèces d'oiseaux lorsque peu d'autres plantes fructifient.

Le Lady Bird Johnson Wildflower Center note que les peuples autochtones cuisinaient et mangeaient les baies, mais qu'« elles sont toxiques en grande quantité » — les pomes contiennent des traces de composés cyanogènes que la cuisson élimine.

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.

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.
