Sanguine Purple Coneflower

Year-round

Sanguine purple coneflower is an easy, clump-forming perennial for sun to part shade.

• It grows in full sun or part shade.
• It prefers well-drained soil that stays a little moist, and needs low water once settled.
• It forms a deep taproot, so choose its spot with care.

Fall

Fall is a good time to plant and the plant winds down.

• Leave seed heads standing if you want seedlings or wildlife value.
• Cut back tired stems if you prefer a neat bed.
• Water new fall plantings until they settle in.

Winter

Winter is dormant and needs almost nothing.

• Skip fertilizer and extra water unless it is very dry.
• Cut back any old stalks left standing.
• Expect new growth from the root in spring.

Spring

Spring is bloom season starting in April.

• Flowers are pink to purple with brown centers and last into July.
• Water new plants during dry spells.
• Planting in spring gives roots time before summer heat.

Summer

In San Antonio summers, established plants need little water.

• Give new plants a deep soak when it is dry.
• Deadhead spent blooms if you do not want seedlings.
• Leave some seed heads if you want to feed wildlife.

Spent brown seed heads can look messy in a front bed, so deadheading keeps it tidy.

Year-round

Sanguine purple coneflower is a tough native prairie perennial from Arkansas, Louisiana, Oklahoma, and Texas. It is not native to Tennessee, but in a Memphis-area yard (zone 8a) it settles in well with full sun and soil that drains, and it gives native bees a real food source through the growing season.

• Plant it in full sun to light afternoon shade, in a spot where water does not sit after rain. Heavy, wet clay through Memphis summers is its main problem.
• Water it regularly the first growing season to help roots establish, then let it lean mostly on rainfall once it is settled in.
• Expect single, softly drooping pink-purple flowers on tall stems, generally April through July.
• It draws native bees, so skip pesticide sprays on it while it is blooming.
• This species is native to the south-central prairies of Arkansas, Louisiana, Oklahoma, and Texas, not to Tennessee, so treat it as a well-adapted garden plant here rather than a local native.

Fall

Fall is cutback and division season for sanguine purple coneflower in Memphis. You can tidy the bed now or leave seed heads up for winter interest and bird food.

• Divide clumps that are three to four years old in fall, while the weather is still mild.
• Cut dead stems back to the ground in fall, or leave the seed heads standing. Goldfinches and other birds feed on them through winter.
• If the plant had eriophyid mites or powdery mildew this year, cut those stems to the ground in fall and clear the debris rather than leaving it in the bed.
• Fall is also a good time to plant new coneflowers, giving roots a head start before next summer's heat.

A neat fall cutback along the front edge of the bed reads as intentional care to a passing HOA inspector, even if a few seed head clusters are left standing further back for the birds.

Winter

Winter is the dormant season for sanguine purple coneflower in Memphis. The plant dies back to the ground and returns from its root crown in spring.

• Standing dead stems and seed heads left up from fall are a winter food source for goldfinches.
• No winter watering or protection is needed. Established plants handle Memphis's zone 8a winters without extra care.
• If the bed was not cut back in fall, late winter, before new spring growth starts, is the last good window to clear old stems.
• Avoid piling mulch on top of the crown. Wet mulch sitting on the crown through a Mid-South winter can lead to rot.

A clean late-winter cutback right before spring growth starts keeps the bed looking tended if standing winter stems have drawn any HOA attention.

Spring

Spring is planting and early-growth season for sanguine purple coneflower in Memphis. New growth pushes up after the last frost, with flower buds forming as the weather warms toward April.

• Plant new coneflowers in spring once the last frost has passed, usually by mid-to-late March in the Memphis area.
• Water new plantings well through spring so roots can establish before summer heat arrives.
• Skip heavy fertilizer. Rich soil makes the plant grow floppy instead of upright.
• Look for the first flower buds forming by mid-to-late spring, with bloom typically starting in April.

Summer

Summer is bloom season for sanguine purple coneflower in Memphis. Once established, the plant handles the region's hot, humid stretches with little help.

• Blooms continue into July in most Memphis-area yards. Watch for drooping pink-purple petals around a dark cone.
• Water only during extended dry spells. Once established this plant is drought tolerant, and overwatering in humid Memphis summers invites root and crown rot.
• Water at the base instead of overhead, to help cut down on powdery mildew in Memphis's humid summers.
• Watch for aphids, Japanese beetles, and powdery mildew, common Mid-South summer issues on coneflowers. Good airflow and spacing help prevent them.
