Overview

Western Tickseed (Coreopsis tripteris) is a tall, sun-loving native perennial with fine, airy foliage and masses of lemon yellow daisies from midsummer into fall. It thrives in full sun and average soils, develops a sturdy clump with short rhizomes, and brings long-season color plus steady pollinator traffic to the back of borders and meadow plantings.

Why You’ll Love It

• Low-maintenance: performs in full sun with modest water after establishment.

• Pollinator-friendly: rich nectar and pollen for bees and butterflies.

• Strong presence: upright stems and clouds of bloom add height and movement.

Ideal Site & Soil

• Sun first: aim for 6 or more hours of direct light for compact, upright growth.

• Drainage matters: prefers dry to medium moisture in loam or sandy loam and tolerates light clay if not wet.

• Wind exposure: choose a site with some shelter or grow with supportive grasses in very windy locations.

Planting Steps

• From pots: set the crown at soil line, backfill, water once to settle, and space 24 to 36 inches for airflow.

• From seed: fall-sow or spring-sow after 30 to 60 days of cold stratification and keep evenly moist until established.

• Establishment: maintain light, regular moisture the first season, then taper.

Care Routine

• Watering: after establishment, water only during extended droughts.

• Feeding: average soils are ideal and high nitrogen can encourage flop.

• Mulch: a thin, airy layer is fine and keep mulch off crowns.

• Pinch or shear: a light pinch at 12 to 18 inches reduces height and increases branching.

• Divide: every 3 to 4 years in early spring if clumps thin or to make new plants.

Design & Companions

• Meadow matrix: weave with Switchgrass (Panicum virgatum), Little Bluestem (Schizachyrium scoparium), and Prairie Dropseed (Sporobolus heterolepis).

• Color partners: Butterfly Weed (Asclepias tuberosa), Purple Coneflower (Echinacea purpurea), and Showy Goldenrod (Solidago speciosa).

• Back-of-border anchor: repeat in small groups for height, rhythm, and a bright late-season finish.

Common Mistakes

• Too much shade: fewer flowers and looser habit.

• Overwatering or rich soil: promotes lodging and taller, softer growth.

• Crowded spacing: limits airflow and increases leaf spotting.

Quick Troubleshooting

• Flopping stems: increase sun, reduce nitrogen, and try a light early pinch.

• Sparse bloom: ensure 6 or more hours of sun and avoid soggy soils.

• Self-sowing more than desired: deadhead most spent sprays before seed drops.

Where It Fits Best
