Hollandia Rose of Sharon Tree

Hollandia Rose of Sharon Tree Form is Hibiscus syriacus 'Hollandia' trained as a single-trunk standard. This deciduous form adds an upright, vase-shaped canopy and summer flowers to the garden. ## Garden Use Plan for roughly 6–8 feet of height and 4–6 feet of width for the standard form. Its raised canopy creates an ornamental-tree accent near an entry, patio, or mixed border while retaining the late-season flowers of Rose of Sharon. ## Growing Conditions Full sun to partial shade suits the species. Use moist, well-drained soil and water regularly while the tree establishes, then provide low to regular irrigation. The species is hardy in USDA zones 5–9 ([NC State Extension profile](https://plants.ces.ncsu.edu/plants/hibiscus-syriacus/common-name/rose-of-sharon/)). ## Seasonal Interest Flowers appear through summer ([Urban Tree Farm's Hollandia standard listing](https://www.urbantreefarm.com/product/hibiscus-syriacus-hollandia-std/)). Green foliage drops in fall, leaving the trained trunk and branching structure visible. ## Maintenance Shape in early spring before new growth and maintain the desired single-trunk outline.
