The shrubby North American native salvias including Salvia greggii and Salvia microphylla are spectacular plants in the fall garden. The same goes form the hybrids between the two species, known as Salvia x jamensis. Here is our clump of Salvia x jamensis ‘Blast’ looking absolutely stunning in late October. Flowering is heaviest in spring, slowing in summer, but again equaling it’s spring show in fall. Hardiness is Zone 7a-9b, and possibly a good bit colder.
