Thryallis
Galphimia glauca
Airy yellow flower sprays nearly year-round in warm winters. Soft evergreen shrub that laughs at heat; tip damage in hard Hill Country freezes but rebounds fast.
Landscape use
Sunny borders, tropical-feel hedges, pollinator beds, and patio screens.
Care
Full sun for best bloom. Low to moderate water. Cut back hard after freezes to renew. Mulch roots in cold snaps.
