Plains Coreopsis

Untreated • Unprocessed • Organic • Non‑GMO

Plains Coreopsis (Coreopsis tinctoria), often called "Calliopsis," is a cheerful, delicate-looking annual that brings a touch of prairie sunshine to any garden. Known for its airy, fern-like foliage and abundance of bright yellow, mahogany-centered blooms, it adds a graceful, rhythmic movement to meadow borders and cottage garden beds. These prolific bloomers are as beautiful as they are resilient, providing a long-lasting display that waves softly in the summer breeze.

Plains Coreopsis is an exceptionally easy-to-grow plant, thriving in well-drained soil and loving the full, intense warmth of the summer sun. Because of its hardy, drought-tolerant nature, it is a perfect candidate for water-wise gardens or areas where other, more demanding flowers might struggle. By choosing our heirloom strains, you are selecting plants that retain the classic, rugged charm and high pollinator-attracting power that have made this native beauty a staple of traditional wildflower meadows.

Frequently Asked Questions

How should I sow them?

They are best direct-sown in early spring or autumn. Simply scatter the seeds over prepared soil and press them down—they need a little light to germinate, so avoid burying them too deeply.

Are they drought-tolerant?

Yes, once they have established a healthy root system, they are quite drought-tolerant. While they appreciate regular moisture during their initial growth phase, they handle dry spells remarkably well.

Do they reseed themselves?

They do! Plains Coreopsis is a prolific self-sower. If you leave the spent flower heads on the plant at the end of the season, they will naturally drop their seeds and often return the following year, creating a lovely, ever-changing wildflower patch.
