Perennial · North Texas care guide
Coreopsis spp.
Nursery Pro tip: Texas-tough yellow that blooms from April into July. Shear it by a third after the first flush for a second round.
Yellow daisies by the hundred from late spring into summer on a tough 1–2 ft native clump. Threadleaf types ('Moonbeam', 'Zagreb') are the most reliable perennials; the large-flowered types are showier but shorter-lived here.
Full sun and drainage; poor soil is fine. Space 18 in apart.
Spring or fall. Hole twice the pot width, ball at grade, native soil, Root Stimulator, thin mulch.
Weekly to establish, then every week or two. Drought tolerant.
Very little.
Shear the whole plant by a third when the first flush fades — that single cut brings a second bloom and keeps it from sprawling. Cut back in late February. Divide every two or three years.
Rot in wet soil. Powdery mildew late in a humid season. Short-lived if pampered; it does better neglected.
Prairie beds with coneflower, black-eyed Susan, salvia and Mexican feather grass. Good in the strip along a driveway.
