Common Name: Coneflower.
Another plant from the prairies of the United States that is known as "Coneflower" (see also Echinacea) because of the prominent central cone that is usually dark brown or green.
They thrive in sun or partial shade and flower for a long period from late July well into autumn. They tolerate drought but are not fussy about soil type.
Propagate by division of clumps in spring. They will set seed but named varieties don't come true.
Deadheading is worthwhile with the early flowers but as flowering comes to an end leave on a few seed heads on the taller varieties to add winter interest. Cut down to just above ground level in late winter.
All are great as cut flowers and all are a great attraction to butterflies.
Named by Linnaeus in honour of his teacher Olaf Rudbeck.
A member of the Asteraceae family.
