Iris barbado

Iris germanica
El clásico iris alemán o lirio común —considerado el antecesor de la mayoría de los cultivares modernos de iris barbado—, probablemente nativo del sur de Europa y el Mediterráneo y ampliamente naturalizado. Cada tallo produce hasta seis flores grandes, generalmente perfumadas, en primavera: tres estándares de color lila erguidos sobre tres caídas moradas marcadas con venas marrones, bases blancas y la característica "barba" amarilla. No tiene bulbo; se extiende por rizomas rastreros que forman grandes matas, con follaje basal en forma de espada de unos dos feet de altura.

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.
