Faits intéressants

Canada Anemone is best planted in larger spaces, rain gardens, or naturalized areas, where it can spread freely and form a dense carpet of white spring blooms. In smaller garden beds, it can quickly outcompete neighbouring plants, but in the right setting, it works well for covering ground and stabilizing moist soils. It tolerates moist conditions and even occasional flooding, making it a strong choice for low areas and stream edges. The white petals are actually sepals, and it attracts early-season pollinators.
