How to prune pineleaf penstemon

After flowering (summer); early spring for removal of winter-damaged stems. After blooms fade, lightly shear the plant by about one-quarter, removing spent flower heads and trimming soft growth to maintain a compact mound. Do not cut back hard into old woody stems, as Penstemon pinifolius does not reliably regenerate from bare wood.

Once after flowering annually; light spring tidy-up as needed. Pineleaf Penstemon is a compact, shrubby evergreen subshrub that benefits from a light shearing after flowering to keep it tidy and promote dense growth. Cut back flower stalks and trim the plant lightly by about one-quarter after blooms fade. Avoid cutting into old woody stems. Remove dead or winter-damaged stems in early spring.
