Echinacea are hardy perennials.
They bloom from the summer until the beginning of autumn with white or red daisy-like flowers.
Common names for Echinacea include Coneflower, Purple Coneflower, and Hedgehog Coneflower.
As they reach heights of between 60 cm and 1.2 M they are ideal for use in garden borders. Echinacea attract bees, birds and butterflies, and make a fantastic dried flower.

If you plan to grow Coneflowers outdoors from seeds then they should be sown at a depth of 3 mm either in autumn or early in Spring. Coneflowers should be grown in a sunny or lightly shaded area of the garden that has good drainage and a soil that has a pH between 5.5 and 7.
If you first plan to grow seedlings of Echinacea species indoors first then they should be started off about 9 or 10 weeks before they are due to be planted out in early autumn or before the last frost of spring.
It usually takes about two to three weeks for Coneflower seeds to germinate in the dark at a temperature of 21 to 24 degrees centigrade. Once ready for transplanted in the garden the Coneflower plants should be spaced at about 30 cm (small) to 60 cm (larger plants) apart.
When Echinacea plants are growing in the garden they require regular watering and the inflorescence stems should be cut back to ground level at the end of autumn. If you require more plants then Coneflower can be divided in the autumn, or cuttings taken from the roots in the spring.
