Description

Firecracker penstemon is aptly named for the bright red flowers that “burst” in abundance along tall flower stocks. Repeated flowering may be encouraged by removing spent flower stocks. The leaves are leathery, deep green and are tightly bunched in a slowly spreading mat. Given sun, well-draining soil and occasional summer water, firecracker penstemon will remain green all year and slowly spread. Since its native range receives consistent summer monsoonal water, firecracker penstemon is tolerant of summer water compared to many penstemon. This penstemon has been a great performer in my area (Sunset zone 15).
