Echinacea, also known as coneflowers, are herbaceous perennial plants that grow up to 140cm high and grow from a short basal stem with fibrous roots. Echinacea produces beautiful composite flower heads during the summer. Other species used as medicine include E. angustifolia and E. pallida.
Echinacea will grow best in a sunny spot and even in lightly shaded areas. Provide average loamy soil with some organic matter, about a neutral pH.
How to Plant
Plants should be at least 40cm apart. When growing from seed you will get better germination rates with 4 to 6 weeks of cold stratification. Sow seeds and cover lightly with soil.
How to Water
Keep the plants moist until they have a few sets of leaves then water once a week when there is no rain. Echinacea is drought tolerant so do not over water.
Grow Echinacea with other flowers, herbs and vegetables including eggplant, broccoli, brussell sprouts, cabbage, cauliflower, chillies, peppers and tomatoes.
How to Propagate
Echinacea can be grown by root division, basal cuttings and clumps can be divided, usually in the autumn or spring.
How to Harvest
Flowers are gathered in full bloom and roots of 3 to 4 year old plants are harvested in the late summer or early autumn.

Echinacea decreased the odds of developing the common cold by 58% and the duration of a cold by 1·4 days on average. Published evidence supports echinacea’s benefit in decreasing the incidence and duration of the common cold. (24)
