Impaciencia

Impatiens walleriana
La «alegría del hogar» — según Missouri Botanical Garden, «la planta anual de jardinería más popular en EE. UU. hoy en día», apreciada por su floración ininterrumpida en sombra donde la mayoría de las anuales languidecen. Perenne tierna de tallos suculentos originaria del África Oriental (Tanzania, Mozambique), se cultiva como anual en todas partes salvo en las zonas USDA 10-11, formando matas de 6-24 inches de alto y cubriéndose de llamativas flores con largo espolón y cinco pétalos en rosa, rosado, rojo, lila, morado, naranja, blanco y bicolores desde junio hasta las heladas. Vale la pena saberlo antes de plantar un parterre entero: la especie es susceptible al mildiu velloso de la impaciencia (Plasmopara obducens), que puede arruinar una plantación.

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.
