Hibiscus syriacus ‘Diana’, commonly known as Rose of Sharon, is a non-native deciduous shrub valued for its large, pure white, single flowers that bloom continuously from midsummer into fall. With a tidy, upright habit reaching 8 to 10 feet tall and 4 to 6 feet wide, ‘Diana’ is ideal for flowering hedges, foundation plantings, or as a focal shrub in sunny garden beds. While it offers long-lasting visual appeal, this cultivar is not native to North America and does not support native pollinators or wildlife as effectively as native hibiscus species.

Why choose ‘Diana’ Rose of Sharon:

• Continuous blooms: Long flowering season from July through fall frost

• Crisp white flowers: Brightens sunny borders with clean, single-petal blooms

• Easy care: Drought tolerant, low-maintenance, and adaptable

Cultivating tips:

• Sun exposure: Requires full sun for best bloom performance

• Soil needs: Grows in most well-drained soils; tolerant of heat and drought

• Maintenance: Prune in early spring to shape and encourage blooms

Designs for your garden:

• Flowering screens: Great for hedges or privacy plantings with summer interest

• Accent shrub: Works well as a specimen in mixed borders or pollinator gardens

• Low-maintenance beds: Reliable structure and color with minimal care

Ecological considerations:

• Non-native shrub: Offers little to no value for native insects or birds

• Not a host plant: Does not support native caterpillars or specialist pollinators

• Use with natives: Combine with native shrubs to balance ornamental and ecological needs
