|RATIBIDA columnifera - Prairie Coneflower|
Asteracea; native to North America.
Germination: Best sown indoors at 60-70° with no cover as light aids in germination. Expect germination in 10-14 days. Seeds can also be sown outdoors in the spring, after all danger of frost is past, in a warm soil. Outdoors, barely cover the seeds.
Growth: Transplant when there are at least two sets of true leaves. Space 6 inches apart in full sun in a neutral to alkaline, moderately fertile, dry, well-drained soil. Fertilize lightly in the spring and if division is necessary, do so at this time. Very tolerant of drought, exposure, wind, heat, humidity, pests, and pollution.
Appearance and Use: A vigorous wildflower for use in borders and naturalized areas alike. It makes a great resident of a rock garden and flowers cut well for fresh use. Growing upright to 3 feet tall by 1 foot wide, it is covered in daisy-like flowers from summer to late fall. The 3 inch diameter flowers have drooping yellow ray florets with a center cone of brown disk florets. The flowers are very attractive to bees. The grayish green, smooth-textured, linear leaves are 11/4-6 inches long by 1/2-3 inches wide.

From a National Gardening Association review:
"Since its [original] publication in 1978, ...Park's Success with Seed has been one of my favorite resources for starting seeds of vegetables, herbs, and flowers."
