Cityline Vienna Bigleaf Hydrangea

Cityline® Vienna is a compact, mounded bigleaf hydrangea with vivid pink or blue summer mopheads, depending on soil pH. It grows about 1–3 feet tall and wide, has sturdy stems and glossy dark-green foliage, and blooms on old wood; Proven Winners identifies the cultivar as ‘Vienna Rawi’ and USPP 10,930, whose patent record is dated June 1, 1999 ([cultivar profile](https://www.provenwinners.com/plants/hydrangea/cityline-vienna-bigleaf-hydrangea-hydrangea-macrophylla); [patent record](https://patents.google.com/patent/USPP10930P/en)). ## Form and Flowers The rounded mopheads are held above a dense, compact outline. The breeder notes strong stems and pink or blue flowers that respond to soil pH. Bloom comes on old wood in early, mid, and late summer. ## Garden Use Use Cityline Vienna in a mixed border, foundation bed, or low hedge, or grow it in a container. The small mature footprint also makes it useful in tighter landscape spaces, and the flowers can be cut or dried. ## Growing Conditions Give it part sun to sun in moist, well-drained soil; average water is adequate once established. It is rated for USDA zones 5–9. In hot sites, provide afternoon shade.

Protect from harsh winter exposure in colder locations.
