Calabacín / zapallo de verano

Cucurbita pepo
La especie única que da origen al zapallo de verano (calabacín, calabaza amarilla cuello torcido, pattypan), al zapallo de invierno tipo bellota, delicata y espagueti, y a la mayoría de las calabazas de tallar y comestibles — las variedades difieren en forma del fruto, tiempo de maduración y capacidad de almacenamiento, pero la biología de la planta es uniforme. Monoica con flores masculinas y femeninas separadas; la polinización por abejas es imprescindible para el cuaje de fruto, y la abeja especialista del zapallo (Peponapis pruinosa) es el polinizador canónico relevante para el cultivo. Requiere alimentación y riego abundantes; suelo rico y humedad constante son fundamentales.

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.
Now
Zone 6b
USDA
Published baseline for this location from 1991-2020.

Well-suited
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.
