Coltsfoot Tussilago farfara Coltsfoot is a distinctive perennial that produces bright yellow flowers in early spring, often before its large, rounded leaves emerge. Its flowers provide one of the earliest available food sources for emerging insects. The plant spreads readily and is best suited to informal naturalized areas where its vigorous growth can be managed. Size at maturity: 6–18" tall, spreading colonies Light: Full sun to part shade Water: Medium moisture Bloom time: February–April Wildlife: Early-season flowers provide nectar and pollen for emerging insects Special features & uses: Very early bloom; naturalizes readily; erosion control; early-season pollinator resource Plant with: Ostrich fern and Tolmeia for a cool, woodland-edge planting, or red-twig dogwood and common rush in a moist naturalized area. Perfect for naturalized plantings, woodland edges, and areas where an early burst of yellow is desired. Because it can spread aggressively, give it room and avoid planting it where containment is important.
