When to plant Cutleaf Coneflower
Cutleaf coneflower is a tall native perennial that bears yellow daisy flowers with drooping petals from late summer into fall (NC State: July to October), spreading aggressively by rhizomes to form colonies. Plant or divide in spring in moist soil in full sun to part shade; leave the dead, hollow stems standing into spring for stem-nesting native bees.
