Description
Penstemon cardinalis is a broadleaf, evergreen perennial with green foliage. In summer, red flowers emerge. Attracts hummingbirds. Grows well with sun and occasional - low water. Drought tolerant once established. Does well in well-drained soil. A good option if you're seeking something verticillium wilt resistant.

Big, deep green leaves form a dashing evergreen rosette up to 3' wide. Needs well drained soil & once established is totally drought tolerant. Excellent choice for rock gardens & dry borders.
