Coreopsis lanceolata

Coreopsis lanceolata: Golden Threadleaf Coreopsis

Cheerful and long-blooming, Coreopsis lanceolata lights up the garden with bright golden-yellow daisy-like blooms that dance above narrow, lance-shaped foliage. One of the earliest coreopsis species to bloom, it begins flowering in late spring and continues well into summer, often reblooming with light deadheading. Its open, airy habit and sunny disposition make it a standout in both naturalistic and more formal designs. Beloved by pollinators, it also thrives in dry, lean soils, making it an exceptional performer in challenging locations.

Plant Characteristics:

• Spread: 30–45 cm
• Flower Colour: Golden yellow
• Flowering Period: Late May to July, with potential rebloom into September
• Foliage: Narrow, lance-shaped green leaves
• Sunlight Requirements: Full sun
• Soil Requirements: Well-drained, sandy to average soils; tolerates drought and poor conditions

Uses and Benefits: Coreopsis lanceolata is ideal for sunny borders, wildflower meadows, slopes, or pollinator gardens where low maintenance and long bloom are essential. It’s excellent for erosion control on banks and thrives in dry, low-fertility soils. A magnet for bees and butterflies, it adds texture, movement, and reliable colour to summer plantings.

Companion Plants: Pair Coreopsis lanceolata with Salvia 'Bumblesnow', Gaillardia 'Mesa Peach', and Sporobolus heterolepsis for a drought-tolerant, pollinator-friendly trio that brings soft texture and rich seasonal contrast to sunny spaces.

Care Instructions: Provide full sun and well-drained soil. Avoid overly rich or wet conditions, which may reduce flowering or encourage floppiness. Deadhead regularly to prolong bloom and consider shearing lightly after the first flush. Divide every few years in spring or early fall to maintain vigour.

History: Native to eastern and central North America, Coreopsis lanceolata is a cornerstone of prairie and meadow plantings. Its adaptability, ease of care, and ecological value have made it a staple in native restoration and pollinator support projects across Canada and the U.S.

Final Thoughts: Radiant, resilient, and richly rewarding, Coreopsis lanceolata delivers effortless summer colour and ecological benefit—perfect for gardeners looking to plant with purpose and joy.
