Purple Pillar® Rose of Sharon

Overview: A hibiscus grown for its purple-violet blooms on a narrow, upright habit.

Mature size: Approximately 8–12 ft. tall and 6–10 ft. wide, unless trained smaller.

Sun exposure: Full sun to light shade

Flowering season: Mid-summer through fall, when many shrubs have finished blooming

Hardiness: USDA Zones 5–9

Water needs: Average; tolerant of heat, humidity, drought, and urban pollution once established

Special features: An unusually narrow, columnar grower, useful where space is tight. Fast-growing, deciduous flowering shrub or small tree; blooms on new wood, so prune in late winter if shaping is needed; can self-seed prolifically — deadhead spent blooms if you want to control spread; foliage emerges late in spring

Wildlife value: Bees, butterflies, and hummingbirds

Botanical name: Hibiscus syriacus 'Gandini Santiago'
