Coreopsis, Firefly

Coreopsis 'Firefly' (Coreopsis verticillata hybrid)
Also known as: Threadleaf Coreopsis 'Firefly'*

Coreopsis 'Firefly' is a long-blooming, airy hybrid perennial known for its soft, pale yellow flowers and fine, thread-like foliage. A cultivar of native threadleaf coreopsis, this selection combines durability and drought tolerance with a light, delicate appearance. Blooming from early summer into fall, it provides consistent color, supports pollinators, and fits beautifully into sunny borders, native gardens, and dry meadows.

Key Characteristics

• Extended Bloom Time for Pollinators
  'Firefly' begins flowering in June and continues through September, offering a steady source of nectar and pollen for native bees, butterflies, and beneficial insects. The open daisy-like flowers are accessible and abundant, making this plant a reliable pollinator support species in dry or sunny gardens.

• Drought-Tolerant and Easy to Grow
  Like its native parent, this cultivar is adapted to dry to medium, well-drained soils and thrives in full sun. Once established, it requires very little care and is ideal for xeriscapes, low-maintenance borders, and native-inspired plantings.

• Fine Texture and Compact Growth
  The threadleaf foliage creates a delicate, ferny texture that contrasts well with bold-leaved plants. 'Firefly' forms a tidy clump 18-24 inches tall and wide, making it a versatile choice for front-of-border plantings, pathways, and meadow edges.

• Great for Meadows, Pollinator Strips & Naturalistic Design
  With its long bloom season and light appearance, this cultivar works well in pollinator strips, dry meadows, and permaculture plantings where extended flower production and habitat value are desired. It can be used in succession planting to carry color from early to late summer.
