Longhead-coneflower

Year-round

Longhead coneflower (Ratibida columnifera), also called Mexican hat, is a native North Texas prairie wildflower that thrives in full sun with very little water once established.

• Plant in a full sun spot; it needs at least 6 hours of direct sun a day to bloom well.
• Water deeply once or twice a week for the first growing season, then let rainfall handle it; established plants tolerate long dry spells.
• Expect a clumping plant 1 to 3 feet tall with wiry stems and small, drooping yellow and brown cone shaped flowers from June through September.
• In heavy black clay, plant it high on a slight mound or work in coarse compost so the crown does not sit in standing water; in the sandier soils west of the metro it drains on its own but will need water more often through its first summer.
• Deadhead spent flower heads through the bloom season to encourage more flowers and to keep the plant from reseeding more than you want.

Fall

Blooming tapers off in fall, which is a good time to let seed heads stand for birds or to divide a crowded clump before winter.

• Let some flower heads dry on the stalk through October; seed eating birds like goldfinches will feed on them.
• For a tidier look, cut spent flower stalks back to the basal leaves by mid November, once blooming has stopped.
• Divide a clump that has spread wider than 2 feet in October or November, replanting the divisions right away.
• Established plants need no supplemental water in fall unless there is an extended dry spell with no rain for a month or more.

Leaving a few seed heads standing reads as a deliberate wildlife planting when paired with a clean edged bed; cut back the rest by mid November if a neater look is preferred going into winter.

Winter

Longhead coneflower goes dormant in winter and needs no care beyond an occasional check after a hard freeze.

• Foliage may brown and die back after the first freeze; this is normal, and the crown survives underground.
• Leave dead stems in place over winter for insect habitat and winter interest, then cut back in late February.
• Skip watering during a typical North Texas winter; only water during an extended dry spell with no rain for 6 or more weeks.
• After a severe Arctic outbreak with hard freezes, check in early spring for new basal growth before assuming the plant died.

Leaving stems standing over winter can look unkempt to neighbors; a low edging or mulch ring around the dormant clump signals it is an intentional bed rather than neglect.

Spring

Spring is the best time to plant longhead coneflower in North Texas, while the soil is still cool and rain is more reliable.

• Plant nursery starts anytime from mid March, after the last frost, through May so roots establish before the July heat arrives.
• Water new plantings 2 to 3 times a week for the first 4 to 6 weeks until you see new growth.
• Cut back any dried stems left over from last year to about 4 inches to make room for new growth.
• Expect the plant to stay low and leafy until late spring, when the first flower stalks appear.

Cutting back old growth in early spring keeps the bed looking tended before the flowering flush starts, reading as an intentional planting rather than a weed patch.

Summer

Summer is peak bloom season, and the deep taproot that formed in spring lets this plant keep flowering through North Texas's hottest, driest weeks.

• Once established, water only during extended dry spells of 3 or more weeks with no rain; overwatering in summer can cause the base to rot.
• Deadhead spent cone shaped flower heads every week or two through July and August to keep new blooms coming.
• If the clump flops open in the center after several bloom cycles, trim the outer stems back to about 12 inches to keep it compact.
• During 100 degree stretches, plants in the sandier soils west of the metro may need a deep soak every 7 to 10 days their first summer; plants in heavy clay usually do not.

Regular deadheading through summer keeps the bed looking maintained during the plant's showiest, most visible season.
