Tickseed (Coreopsis ‘Limerock Ruby’)
Tickseed
Coreopsis is a genus of between 75-80 species from North America, Mexico, Central and South America.
The genus name comes from the Greek words koris meaning “bug” and opsis meaning “like” in reference to the shape of the seed which resembles a bug or tick.
‘Limerock Ruby’ is an unusual red-flowered hybrid coreopsis that most resembles threadleaf coreopsis (C. verticillata) in form. It is a chance seedling resulting from a random cross-pollination of unidentified selections of C. rosea and C. verticillata. It is a rhizomatous perennial that typically grows in dense, bushy clumps to 8-12” tall. Ruby-red daisy-like flowers (to 5” diameter) with untoothed red rays and yellowish centers appear singly above the foliage mound on slender self-supporting stems to 12-18” tall. Long late spring to late summer bloom period that sometimes extends to first frost. Shearing plants in mid-summer (early August) when bloom usually tapers down will encourage a fall rebloom. Palmately 3-parted leaves with thread-like segments lend a fine-textured and airy appearance to the plant. Plants in the genus Coreopsis are sometimes commonly called tickseed in reference to the resemblance of the seeds to ticks. U.S. Plant Patent PP15,455 issued December 28, 200 Originally introduced as being quite winter hardy but has proven to be winter hardy only in the deep south.
Easily grown in dry to medium moisture, well-drained soils in full sun. Tolerant of heat, humidity and some drought. Plants may be sheared in mid to late summer to promote a fall rebloom and to remove any sprawling or unkempt foliage. Plants may spread by rhizomes. Clumps may be divided in spring. When grown in borders or other formal garden areas, division may be needed every 2-3 years to maintain robustness.
Hardiness and longevity of hybrid coreopsis depends greatly on parentage, and ranges from hardy, fully perennial selections to half-hardy or tender perennials more often grown as annuals.
| Hardiness zone | 8 - 9 |
| Sun light | Full Sun |
| Water | Dry To Medium |

Crown rot may occur if grown in moist, poorly drained soils. Uncommon diseases include botrytis, aster yellows, powdery mildew and fungal spots. Plant stems tend to sprawl, particularly in hot and humid climates with periodic heavy summer rainfall. Deer tend to avoid this plant.
Border fronts. Sidewalk edgings. Also effective in naturalized areas, wild gardens or cottage gardens. Good plant for areas with poor, dry soils. Patio containers.
