Whitecaps Stoke Aster is a hardy perennial known for its large fringed blue flowers over evergreen rosettes. Whitecaps Stoke Aster flowers in summer in shades of blue, and performs best in full sun with moderate watering once established. This perennial matures to roughly 1-2 feet tall and 12-18 inches wide. It is ideal for planting in drifts through a border, or as a reliable cut flower, offering dependable colour that returns every year. Well suited to the Canadian climate in zones 5-9, it establishes readily and improves with age. A layer of mulch helps hold moisture and keeps roots cool in summer.
