Asperge
Asparagus officinalis
Une vivace herbacée à longue durée de vie, cultivée pour ses jeunes turions tendres récoltés en avril et mai avant qu'ils ne se déploient. Originaire d'Europe et d'Asie tempérée, elle pousse à partir d'une couronne qui demande 2-3 ans pour entrer en production, mais produit ensuite pendant quinze ans ou plus. Les turions non récoltés se développent en fougères légères et aériennes de 3-4 feet en été ; les plants sont dioïques, et les plants femelles produisent de beaux fruits rouges ornementaux à la fin de l'été.

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.
