Ontario Blazing Star is a hardy perennial known for its bottlebrush spires that open top-down and draw butterflies. Ontario Blazing Star flowers in mid to late summer in shades of purple, and performs best in full sun with low watering once established. This perennial matures to roughly 2-4 feet tall and 12-18 inches wide. It is ideal for perennial borders, cottage gardens, and pollinator plantings, offering dependable colour that returns every year. Well suited to the Canadian climate in zones 3-9, it establishes readily and improves with age. It tolerates dry spells well once its roots are down.
