Whorled Coreopsis
Coreopsis verticillata
Whorled Coreopsis, also known as Threadleaf Coreopsis or Whorled Tickseed, is a garden favorite for its vibrant displays of star-shaped, golden-yellow flowers that bloom from early summer to fall. This plant's fine, thread-like leaves create a delicate texture that contrasts beautifully with its bold blooms. Standing about 1 to 2 feet tall, it's an excellent choice for borders, rock gardens, and cottage gardens. This drought-tolerant species thrives in full sun and well-drained soil, making it a resilient addition to any landscape. Its flowers are not only a visual delight but also a vital nectar source for bees and butterflies, playing a crucial role in supporting local ecosystems.

Maintenance Tips
- Drought-tolerant once established; water moderately until then.
- Deadhead to encourage reblooming and prevent self-seeding if not desired.
- Prefers well-drained, sandy or loamy soils; avoid overly wet conditions.
- Divide clumps every 2-3 years in the spring to maintain vigor and spread.
- Keep an eye out for pests, although it's generally low-maintenance and disease-resistant.
