Rosa blanca
Rosa x alba
Un antiguo grupo híbrido europeo de rosa antigua de jardín (la 'x' marca su origen híbrido); las rosas alba o 'blancas' incluyen la histórica Rosa Blanca de York. Es un arbusto resistente, de porte erguido a arqueado, de 5-8 feet, excepcionalmente resistente al frío y mucho más resistente a las enfermedades que las modernas híbridas de té, con flores fragantes de color blanco a rosa suave sobre un follaje distintivo verde azulado. Honestamente, florece una sola vez — una única y generosa floración a comienzos del verano que no se repite — seguida de escaramujos rojos en otoño. De manera inusual para una rosa, tolera la semisombra y el suelo pobre, lo que la hace indulgente en sitios donde fracasan las rosas más exigentes. Los escaramujos y los pétalos son comestibles (conservas, jarabes, agua de rosas), y las flores fragantes atraen a las abejas. No es maleza ni invasora; es simplemente un arbusto de jardín muy antiguo y muy duradero.

Cultivada principalmente como ornamental fragante, pero sus escaramujos y pétalos son comestibles: los escaramujos rojos se usan para conservas, jarabes y té (muy ricos en vitamina C), y los pétalos fragantes para agua de rosas, jarabes y conservas.
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.

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.
