Verbena de Buenos Aires
Verbena bonariensis
Un ornamental aéreo y transparente de la familia de las verbenas (Verbenaceae), nativo de América del Sur y naturalizado en gran parte del cálido sureste de los Estados Unidos. NC State Extension describe una planta erguida de 2-5 feet de altura sobre tallos delgados pero resistentes de color verde con marcas rojas, coronados desde el verano hasta el otoño por densos racimos planos y redondeados de pequeñas flores tubulares de color morado-lavanda, muy por encima de hojas predominantemente basales, lanceoladas, dentadas y de color verde oscuro. Perenne en las zonas USDA 7-11 (cultivada como anual en climas más fríos), es de rápido crecimiento, tolerante a la sequía y a los ciervos, y un imán para abejas, mariposas y colibríes — aunque se autosembra libremente y algunas fuentes la han calificado de invasora.

2050
Zone 7a
Plotwright
Projected zone for this same location in 2050 (2041-2070) using SSP3-7.0 (regional rivalry).
Marginal
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, but marginally possible by 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.
