Romero
Salvia rosmarinus
Un subarbusto aromático siempreverde de origen mediterráneo, conocido durante mucho tiempo como Rosmarinus officinalis (reclasificado como Salvia rosmarinus en 2017 con base en filogenia molecular). Muy tolerante a la sequía una vez establecido; flores de color azul pálido en primavera; follaje cosechado durante todo el año en climas cálidos como la hierba culinaria mediterránea por excelencia. En zonas inferiores a la 7, su rusticidad es límite — se pasa al interior en invierno o se trata como anual fuera de las zonas 8-10.

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.

Mediterranean drought-tolerant edible
A low-water edible palette of culinary herbs + a hardy grape for hot dry sunny sites. Mediterranean-origin plants thrive on neglect; their primary failure mode is overwatering, not underwatering.
