Marina Blue Satin Rose of Sharon

Marina is the cultivar behind Blue Satin® Rose of Sharon, a deciduous Hibiscus syriacus with large deep-blue flowers, reddish-purple throats and prominent creamy-white staminal columns. This upright shrub flowers from midsummer into fall. ## Garden Use Use Marina in a sunny shrub border, screen, or flowering hedge. The [Chicago Botanic Garden profile](https://www.chicagobotanic.org/plant-information/plant-finder/hibiscus-syriacus-marina-rose-sharon) gives a mature height of 6–9 feet, USDA zones 5–9, and full-sun exposure; it identifies Blue Satin® as the trademark name for this cultivar. Red Butte Garden describes a mature spread around 4½ feet, so allow room for a shrub about 4–6 feet wide. The [cultivar patent record](https://www.hort.net/pedia/patent/grant/12680/) names ‘Marina’ and describes its upright, freely branching habit and violet-blue flowers. ## Growing Notes Plant in well-drained soil and provide full sun for the strongest flowering. The large flowers have creamy staminal columns and contrasting reddish-purple throats. ## Maintenance Water while establishing and during prolonged dry spells. Prune in early spring if shaping is needed; rose of Sharon flowers on new wood, so this timing leaves the season’s growth available for blooms.
