Hibiscus de Chine
Hibiscus rosa-sinensis
Un arbuste tropical fragile à feuillage persistant cultivé pour ses fleurs énormes et flamboyantes : de larges entonnoirs rouges, roses, orange, jaunes ou blancs, simples ou doubles, chacun portant une longue colonne saillante d'étamines soudées. Originaire d'Asie tropicale (un cultigène d'une culture si ancienne qu'aucune origine sauvage certaine ne subsiste), Hibiscus rosa-sinensis fleurit en continu à la chaleur au-dessus d'un feuillage brillant, vert foncé et persistant. Chaque fleur ne dure généralement qu'une journée, mais une plante saine ouvre de nouvelles fleurs en succession régulière du printemps à l'automne — et toute l'année dans les climats sans gel. C'est l'hibiscus classique des paysages de climat chaud et des bacs de terrasse : amateur de chaleur et d'humidité, sensible au gel, et rustique en pleine terre uniquement dans les zones USDA 9a-11b.

Hibiscus rosa-sinensis n'est pas toxique, et ses fleurs sont comestibles : on les utilise fraîches en garniture et on les infuse, comme les autres hibiscus, pour des tisanes et des boissons.
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.
