Comment:

Coreopsis verticillata, commonly called threadleaf coreopsis or whorled coreopsis, is a rhizomatous perennial which typically grows in dense, bushy clumps to 1-3' tall.

Plants in the genus Coreopsis are sometimes commonly called tickseed in reference to the resemblance of the seeds to ticks.

This plant would be beautiful with its fine foliage even if it never flowered;

Regions:  Mountain, Piedmont, Coastal plains

Seasons of Interest: 

  Blooms:   Summer           Nut/Fruit/Seed:  Late summer

Wildlife Value:  This plant is highly resistant to damage by deer.  Its flowers are attractive to butterflies and other pollinators.  Its seeds are eaten by songbirds.

Insects, Diseases, or Other Plant Problems: Slugs and snails may occur. This plant tends to sprawl, particularly if grown in moist and/or fertile soils. Crown rot may occur if grown in moist, poorly drained soils. Uncommon diseases include botrytis, aster yellows, powdery mildew and fungal spots.

 

Season:
Summer
Height:
6-36 in.
Flower Color:
Soft yellow, gold
Hardiness:
USDA Hardiness Zone 3-9
Foliage:
Threadleaf coreopsis has palmately 3-parted leaves with thread-like segments lend a fine-textured and airy appearance to the plant. Whorled leaves divided into narrow segments.
Flower:
The Threadleaf coreopsis has yellow, daisy-like flowers (1-2" diameter) with yellow untoothed rays and yellow center disks. The flowers appear singly in loose clusters (cymes) in a profuse and lengthy late spring to late summer bloom. Shearing plants in mid-summer will promote a fall rebloom.
Site:
Threadleaf coreopsis is easily grown in dry to medium moisture, well-drained soil in full sun. It thrives in poor, sandy or rocky soils with good drainage. It is tolerant of heat, humidity, and drought. Prompt deadheading of spent flower stalks can be tedious for a large planting, but does tend to encourage additional bloom and prevent any unwanted self-seeding. Plants may be sheared in mid to late summer to promote a fall rebloom and to remove any sprawling or unkempt foliage. Species plants can spread somewhat aggressively in the garden by both rhizomes and self-seeding.
