Ratibida pinnata, also known as gray-headed coneflower, is a perennial wildflower native to Michigan and the UP.
Plant reaches 5 feet tall and flowers from July to September with a grey-centered yellow blossom. It grows readily and naturalizes well in open, sunny spaces. Use it in a spot where the soil is poor and other plants are difficult to grow. In a bed, grow them in mass plantings, as individual plants are thin and a little scraggly. It pairs well with purple coneflower. Grey Headed Conflower prefers full sun to partial shade, medium to dry soil and will grow in muck, clay, loam or sand.
Native bees and butterflies are highly attracted to grey-headed coneflowers. Some of the native bees that commonly use grey-headed coneflowers are sweat bees, bumble bees, long-horned bees, and leafcutter bees. Butterflies such as viceroys, monarchs, azures, sulphurs, crescents, and hairstreaks will commonly visit grey-headed coneflowers. Grey-headed coneflowers are also host plants for the caterpillar of the wavy-lined moth. After the flowers go to seed, goldfinches and other songbirds will eat the seeds.
Single plants will come in plastic pots (Approx. 4” x 4 .5”) Plants will vary in size between 2 and 10 inches. Single Species plug flats will be 2" x 5" plugs in 38 cell flats.
