Plants are dispatched in growing condition and may not be in full flower. If too tall to pack safely, we may cut them back — this helps them establish more quickly. Read our Mail Order FAQs.
Penstemon glaber ‘Roundway Snowflake’ bears small, pure white tubular flowers with protruding stamens from summer into autumn. It has a shrub-like habit with upright stems and narrow, glossy green, lance-shaped leaves.
It suits the front or middle of a white border, growing well in sun or very light shade in fertile, free-draining soil.
Hardiness: H4 (−10°C to −5°C). Hardy through most UK winters. Provide winter protection in colder inland, upland or northern gardens; plants in pots are more vulnerable to frost.
Height × Spread: 45cm × 45cm
