Lupino de Texas
Lupinus texensis
La emblemática flor estatal de Texas: una planta anual leguminosa de invierno y primavera, baja y de porte amontonado, que alfombra de azul los bordes de las carreteras, los campos y las laderas del centro de Texas. A partir de una siembra de otoño pasa el invierno como una roseta baja y luego, en primavera, levanta densas espigas cónicas de flores fragantes parecidas a las del guisante, de un azul intenso con un ojo blanco (que envejece a púrpura rojizo) en el pétalo superior. Nativa de Texas y de unas pocas áreas adyacentes, es la especie tras los famosos despliegues primaverales de bluebonnet. Como leguminosa fija su propio nitrógeno y se resiembra con facilidad, prosperando en suelos pobres, secos, gravosos y a menudo alcalinos a pleno sol: las condiciones magras que vencen a flores más exigentes. Una advertencia de peso: como otros lupinos, el lupino de Texas es TÓXICO. Sus semillas y follaje contienen alcaloides quinolizidínicos venenosos para el ganado y las personas, así que es una flor para admirar, no para comer. Plántela por el espectáculo primaveral y por las abejas, manténgala donde los niños y los animales de pastoreo no la ramoneen, y déjela resembrarse para el año siguiente.

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.
