ëPinwheel is a hybrid perennial coreopsis that typically grows in a mound to 24î tall and 30î wide. Light yellow pinwheel-shaped flowers (to 1.5î diameter) with orange centers bloom, often in profusion, from early summer to fall over a mound of blue-green leaves. Plants in the genus Coreopsis are sometimes commonly called tickseed in reference to the resemblance of the seeds to ticks. U. S. Plant Patent Applied For (PPAF).
- Full sun
- Dry to medium
Easily grown in dry to medium moisture, well-drained soils in full sun. Although established plants tolerate some soil dryness, best performance generally occurs in soils that are given consistent and regular moisture throughout the growing season. Avoid poorly-drained, heavy clay soils. Prompt deadheading of spent flower stalks can be tedious for large plantings, but does tend to encourage additional bloom. If bloom ceases in mid to late summer, plants may be sheared to promote a fall bloom and to tidy the planting. Plants are reportedly sterile, so self-seeding is not a problem. Clumps may be divided in spring.
