Rudbeckia maxima or Great Coneflower, is a herbaceous perennial in the daisy family that is easily grown in average, moist, well-drained soils in full sun. It is an easy-going plant that tolerates light shade, heat, some drought, nighttime visits from deer, and a wide range of soils. It can be grown from seed, but in ideal growing conditions, it will self-seed. It also propagates itself through rhizomes. Plant it in along a border, in a cutting, pollinator, or cottage garden or in a meadow or naturalized area. The flower stalks rise to 7 feet bearing intense yellow-rayed flowers. Each flower is about 3 inches with drooping rays and a 2 to 6 inch dark brown central cone. After the blooms go to seed, it will attract songbirds including goldfinches. This is just an impressive bloom that is sure to get attention.

Planting Instructions:

Direct sow these seeds in late fall pressing into the surface of the soil since the plant needs light to germinate. For spring planting, mix seeds with moist sand and store in the refrigerator for 30 days before planting. Keep the soil moist until germination which usually occurs in 3 weeks. The seeds can also be started indoors and transplanted after the threat of frost in the spring. Keep seedlings lightly moist. Once established, they will need little care and can tolerate some drought.
