Bégonia des jardins
Begonia (Semperflorens Group)
Une vivace tendre cultivée presque partout comme annuelle de massif de saison chaude, appréciée pour sa floraison fiable de juin jusqu'aux gelées en blanc, rose, rouge et bicolore. Ses feuilles épaisses, cireuses, vert sombre à bronze réduisent les pertes en eau, lui conférant une vraie tolérance aux étés chauds et humides. Compact et en dôme de 6-12 inches, c'est une plante de bordure infatigable et un excellent remplissage de bac en mi-ombre ensoleillée.

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.
