Care

Best grown in acidic, organically rich, humusy, moisture-retentive but well-drained soils in part shade. Roots must never be allowed to dry out. Shallow, fibrous root systems benefit greatly from mulch.

Maintenance

Clip off spent flower clusters immediately after bloom as practicable. Do not cultivate around plants.

Cleanup

Remove faded blooms to maintain appearance; deadhead spent flowers promptly.

Notes

A Gable hybrid developed by the late Joseph Gable of Stewartstown, Pennsylvania.
