How to Start It
★ Recommended for beginners
Echinacea seed sprouts best after a cold spell, so the easiest way is to sow it outdoors in late fall and let winter do the work. Press the seeds into the soil about 0.5 cm deep and mark the spot. They sprout in spring, usually in 10 to 20 days once the soil warms: thin them to about 30 cm apart. Most plants flower in their second summer.
Echinacea is a tough prairie flower that comes back every year, handles drought and poor soil, and feeds bees and butterflies all summer. Leave the seed heads standing in winter, because goldfinches love them.

Growing Tips
- 1Plant echinacea in full sun, at least 6 hours a day.
- 2It likes ordinary, well-drained soil, so add just a little compost and never let it sit in soggy ground.
- 3Water young plants weekly in their first summer, then only in long dry spells, since established plants handle drought well.
- 4Skip extra feeding, because rich soil makes floppy stems and fewer flowers.
- 5Spray aphids off with a strong stream of water, and keep plants 30 cm apart so air moves between them.
- 6Leave the stems standing over winter for the birds, and cut them down in early spring.

How to Harvest
- 1Cut flowers for a vase in the cool of the morning, with long stems, when the petals have just opened.
- 2Snip off faded flowers in summer to get more blooms, but stop in late summer and leave the last seed heads for the birds.
- 3Many people dry the petals and leaves for tea: pick them on a dry morning and hang small bunches upside down in a shady, airy spot.
- 4Store the dried pieces in a sealed jar away from light.
Step 5
Saving Seeds
How to Save Seeds
Echinacea is pollinated by insects and crosses with other echinacea nearby, so seed from a named variety often grows into plants that look different, and hybrid F1 seeds will not grow true. Plain purple coneflower grown on its own gives seedlings very close to the parent. Leave the seed heads on the plant until they are dark brown and dry in fall, then cut them, wearing gloves because they are prickly. Pull the heads apart over a bowl to free the small, wedge-shaped seeds. Store them labelled in a cool, dark, dry place, where they keep 2 to 3 years.
