Red Trillium is a hardy perennial known for its Ontario’s provincial flower, a treasure of the spring woodland. Red Trillium flowers in spring in shades of red, and performs best in part shade with moderate watering once established. This perennial matures to roughly 12-18 inches tall and 12-18 inches wide. It is ideal for perennial borders, cottage gardens, and pollinator plantings, offering dependable colour that returns every year. Easy to establish and simple to maintain, Red Trillium rewards basic care with a reliable display season after season. A layer of mulch helps hold moisture and keeps roots cool in summer.
