Pastèque
Citrullus lanatus
Une liane annuelle rampante originaire du sud-ouest de l'Afrique, cultivée dans le monde entier pour ses fruits sucrés et juteux d'été. Des tiges poilues et prostrées garnies de vrilles bouclées s'étendent sur 10 feet ou plus au sol, portant des feuilles profondément pennatilobées et de petites fleurs vert pâle. Elle nécessite de longs étés chauds ainsi qu'un sol riche, constamment humide et bien drainé ; des abeilles sont indispensables pour polliniser les fleurs femelles et produire les melons sphériques à ovales aux rayures sombres.

2050
Zone 7a
Plotwright
Projected zone for this same location in 2050 (2041-2070) using SSP3-7.0 (regional rivalry).
Well-suited
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.
✓
Well-suited today and still thriving 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.
