Goldenmane Tickseed

About

Goldenmane tickseed (Coreopsis basalis) is a showy annual or short-lived coreopsis of prairies, roadsides, and open sandy ground in the south-central United States and adjacent regions, with dark-centered gold ray flowers and fine foliage that self-sows politely in warm climates. It is a pollinator snack bar in spring-to-summer windows when many beds are still deciding their personality. Use it in meadow mixes, rain-garden margins with sharp drainage, and chop-and-drop annual rotations that refuse turf monoculture. ☀️💧 Sun and Water Requirements: Full sun; lean, well-drained soils produce compact plants and intense bloom. Tolerates drought once established but looks fuller with moderate moisture between rains. Poor performance in heavy wet clay without amendment. Not reliably perennial in cold zones—treat as self-seeding annual northward. ✂️ Propagation: Sow seed directly after frost risk; barely cover—light aids germination. Collect dry heads before shatter to curate color placement next season. 🌾 Harvest / Best Use Timing: Cut flowers for bouquets at early open stage; deadhead to prolong bloom or allow seed for finches and self-sowing.

Permaculture Functions

• Pollinator: Ray and disk flowers support small bees, hoverflies, and butterflies in sunny beds.
• Ornamental: Dark-centered gold blooms give high contrast in wildflower designs.
• Ground Cover: Dense annual mats exclude some weeds in disturbed sunny niches.
• Wildlife Attractor: Seeds feed songbirds when heads mature; flowers feed diverse insects.

Practitioner Notes

• Dark disk centers are the ID handshake—if the center is plain yellow, negotiate species names before tagging.
• Self-sowing is gentle until it is not—mulch or edit volunteers where order matters.
• Finches treat seed heads like vending machines—leave some if you like bird TV.
• Wet clay without drainage is a funeral plot—Coreopsis wants air at the roots.
