Red Pillar® Rose of Sharon

Red Pillar® is a narrow, upright Rose of Sharon selection with reddish-pink flowers and large, deep-red centers. Its columnar form brings summer color to a sunny hedge, screen, or specimen planting. ## Site and Growing Grow in full sun and well-drained soil. Proven Winners lists USDA Zones 5–9 and mature dimensions of 10–16 feet tall by 4–5 feet wide. Water regularly while the shrub establishes; its profile describes drought tolerance after establishment and notes that regular pruning is unnecessary. The narrow form naturally needs little shaping, and any optional pruning is best done in early spring. The [Proven Winners profile](https://admin.provenwinners.com/plants/hibiscus/red-pillar-rose-sharon-hibiscus-syriacus) identifies the cultivar as ‘GFNHSRP’, gives the mature size and hardiness range, and describes its reddish-pink flowers with red centers. The [plant patent](https://patents.justia.com/patent/PP35332) confirms the denomination, columnar habit, and reddish-pink flowers with a deep-red eye. ## Maintenance Keep mulch over the root zone but away from the stems. Remove damaged branches as needed, and prune only if shaping is necessary. In snowy areas, choose a position away from roof snow shedding.
