Coreopsis Seeds

Learn about Coreopsis Seed

A common name for coreopsis is tickseed, because at first glance the seeds resemble ticks. The name coreopsis comes from the Greek words, koris (meaning bedbug) and opsis (meaning view). This refers to the shape of the plant's dry fruit. Just to be clear, coreopsis' nickname comes from the visual comparison only and rest assured, this floral species does not attract ticks. It does however attract pollinators like bees and hummingbirds!

Coreopsis forms upright clumps of showy flower heads, and is native to North, central, and South America. It's even the state wildflower of Florida! This species is low maintenance, drought tolerant, long blooming, and rugged. You'll most commonly find these blooms on roadsides, fields, and gardens throughout the spring and summer. Additionally, starting your own coreopsis plants requires little maintenance and you can expect them to bloom during their first growing season! Coreopsis is drought tolerant and poor soil tolerant, as well as deer resistant and rabbit resistant!

Coreopsis Planting Information

Start coreopsis seeds indoors six to eight weeks before the last spring frost, or sow directly into your garden after all threats of frost have passed. Coreopsis thrives in dry to medium moisture, well-drained soils with full sun exposure. Sow the seeds and cover lightly, as coreopsis requires sunlight to germinate properly. Seeds will germinate within 21 to 28 days.

When sowing outdoors or when transplanting seedlings outdoors, space the plants approximately eight to twelve inches apart. Coreopsis plants will reach full maturity about 60 to 90 days after seeds are sown. Be sure to water regularly and sow additional seeds every few weeks for more continuous blooms.

Cut back coreopsis plants in the summer if the foliage becomes unkempt. You may also deadhead spent flowers to encourage additional blooming and prevent unwanted self-seeding. Once your coreopsis plants are established in the garden, divide clumps every two to three years.
