Coreopsis Flower Seeds Packet
Big Flower Coreopsis (Coreopsis grandiflora) is a drought-tolerant perennial that bursts into large golden-yellow, daisy-like blooms through the hottest weeks of summer. It thrives in poor soil with very little attention, attracts bees, butterflies, and other beneficial insects, and is a beautiful choice for flower beds, borders, cottage gardens, wildflower meadows, containers, and cut flower bouquets. Seeds are non-GMO and vacuum-sealed for freshness.

How to Grow Coreopsis from Seed
Sowing and Germination
Direct sow after the last frost, or start indoors in seed trays 6-8 weeks earlier. Surface sow and press the seeds lightly into the soil without covering them, since they need light to germinate. Keep the soil moist until seedlings are established.
Care and Harvest
Water moderately while plants establish, then give an occasional deep watering once mature. Go easy on fertilizer: a light balanced feeding in spring is plenty, as too much produces leaves instead of flowers. Remove spent blooms to keep flowers coming (this also limits self-seeding), and cut plants back in late summer for a second flush of blooms. In fall, leave a few seed heads for the birds or trim back for tidiness. To save seed, let some heads dry on the plant and store the seeds in a cool, dry place.

Standard paper seed packets are permeable to oxygen and moisture -- the two primary causes of seed degradation. Most paper-packaged seeds begin losing germination viability after approximately one year, contributing to significant garden-industry waste: packets purchased, not planted, expired, discarded. Shido Seeds are hermetically vacuum-sealed. The packet does not expire quietly in a drawer. It waits.
Every Shido seed packet is illustrated in the style of Japanese 1910s woodblock printing -- designed and drawn in-house by Chive, the Toronto ceramics studio that has been exhibiting at the Chelsea Flower Show in London every year and does not, as a matter of principle, sell to big-box retailers. Customers collect the packets as a series. This was not the original plan.
