Ajo silvestre americano (ramps)

Allium tricoccum
Una planta efímera de primavera, pariente silvestre del puerro, propia de los bosques caducifolios ricos y húmedos del este de América del Norte: el primer verde comestible que alfombra el suelo del bosque cada primavera con amplias hojas basales lisas y perfumadas como el puerro. El follaje se marchita a principios de verano, momento en que emerge un escapo sin hojas que eleva por encima de la hojarasca una umbela redondeada de pequeñas flores blancas. Muy apreciada, aunque intensamente sobrecolectada como planta silvestre comestible, por lo que conviene cultivarla deliberadamente a la sombra profunda del bosque.

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.
