Rough Coneflower

Year-round

Rough coneflower is a tall, clump-forming perennial wildflower in the sunflower family, native to prairies, roadsides, and dry open woods across the south-central United States. It produces bright yellow daisy-like blooms with a dark, cone-shaped center from midsummer into late summer.

• Give it full sun and well-drained, dry to average soil; it thrives in dry conditions and does not need supplemental irrigation once established.
• It can reach up to about 4 feet tall, so give it room at the back of a bed or in a naturalized planting.
• It forms a clump rather than spreading aggressively, making it easier to place than many prairie perennials.
• No regular fertilizing is needed; it is adapted to average to lean, dry soils.

Its upright, clump-forming habit and long midsummer bloom read as an intentional prairie-style planting rather than an overgrown bed.

Fall

Bloom has typically finished by fall; the plant sets seed and foliage begins to decline.

• Let seed heads mature and stand through fall if you want the planting to feed birds and self-seed naturally.
• No watering is typically needed; the plant is adapted to dry conditions and does not require fall irrigation.
• No feeding is needed this late in the season.

Winter

Top growth dies back over winter; the plant persists as a dormant clump and any dropped seed.

• Cut back dead stems in late winter or leave them standing as habitat and winter structure, then clear before spring growth resumes.
• No watering is needed while the plant is dormant.
• Expect the clump to resprout from its base once soil warms in spring.

Cutting back dead stems in late winter keeps a naturalized planting looking cared for rather than untidy.

Spring

Spring is a growth phase; foliage emerges and expands ahead of the midsummer bloom.

• Water occasionally during a dry spring to help new growth establish, then taper off as the plant matures.
• No pruning is needed at this stage; let the clump fill in.
• Avoid rich, amended soil or heavy fertilizer, which can cause floppy growth in a plant adapted to lean, dry ground.

Summer

Bloom runs through July and August, with bright yellow, dark-centered flower heads opening on tall stems.

• Once established, it tolerates heat and dry stretches well and rarely needs watering beyond natural rainfall.
• Deadheading is optional; leaving spent blooms provides seed for native bees and birds later in the season.
• Its blooms offer significant value to native bees, so avoid spraying insecticides nearby during bloom.
