Nice, bushy plants that will be completely covered in buttery yellow flowers in early summer. Tough as nails once established. It has a reputation for aggressiveness, but I've had it in my garden for three years without any problem.

Prairie coreopsis is a perennial plant from 1 to 3 feet tall. Found in dry prairies, glades, open woods and roadsides. Associated with acid soils. Cool moist stratification or seeds improves germination. This plant can be aggressive if not planted with competitive species.

Easily grown in dry to medium wet, well-drained soil in full sun. Thrives in poor, sandy or rocky soils with good drainage. Tolerant of heat, humidity and drought. Prompt deadheading of spent flower stalks encourages additional bloom and prevents any unwanted self-seeding. Spreads by rhizomes and self-seeding, and in optimum growing conditions will naturalize to form large colonies. Plants may be cut back hard in summer if foliage sprawls or becomes unkempt. If grown in borders, division may be needed every 2-3 years to maintain robustness.
