'Purple Emperor' produces large, saturated magenta purple blossoms on sturdy, well-branched stems that are held in perfect proportion to the bushy clump of deep green foliage. As the flowers age, the tips of the petals turn a bit lighter pink but the center remains a bright magenta color. Praised for their cheerful brightly colored flowers, coneflowers are a mainstay in today's garden. Be sure to leave some spent blooms on the plants in the fall because their seeds provide winter food for finches and other birds. The dried seed heads also provide architectural interest in the winter.
Thrives in full sun. Plant in well-drained soil. Cut off spent blooms to encourage new blooms or leave flower heads in place for birds to enjoy in the fall and winter. Feed yearly with an organic fertilizer. Cut back to near ground level in late fall after a hard freeze.
