HOW TO GROW

Sowing: Direct sow in late fall, planting the seed just below the surface of the soil; these large flowered tickseed seeds need light to germinate. For spring planting, mix the seed with moist sand and store it in the refrigerator for 30 days before direct sowing. Keep the soil evenly moist until germination, which should occur within 10-15 days. The treated Coreopsis Grandiflora seeds can also be started indoors 6-8 weeks before the last frost of spring; plant the seeds on the surface of a flat, keeping the moisture consistent and the temperature around 65 degrees F. Transplant seedlings.

Growing: This plant adapts to nearly any soil, including rocky or shallow areas or seaside conditions. Water the seedlings occasionally until they become established; mature plants prefer dry soil and tolerate drought, heat, and humidity well. If given too much moisture or rich soil, the plants tend to flop and may need support. If the blooming decreases midseason, cut the plant back by half for new growth and blooms. Regular deadheading also helps prolong the season of blooming. If allowed to self-seed it will produce volunteer plants, though it does not become weedy. For the healthiest growth, divide plants in the spring or fall after several years of growth. This plant attracts butterflies and bees as well as resisting rabbits and deer.

Harvesting: For long lasting fresh flowers, cut the stems long and place them in water immediately.

Seed Saving: Several weeks after the flowers have faded, the seed heads will turn dry and dark brown. Since these seeds are a favorite food of songbirds and rodents, harvest them promptly. Cut the heads from the plant and spread them out to dry completely. Break them apart to remove the Coreopsis Grandiflora seeds and separate the seeds from the chaff. Store the large flowered tickseed seeds in a cool, dry place.

Review By Larbe Flowered Tickseed

Always quality seeds

I haven't used these seeds yet, but I am very pleased with all of my purchases from Everwilde. I buy my seeds here because they provide good planting instructions and often have pictures of cotyledon and first leaves especially helpful when planting wildflower beds.

Great selection filters for native plants

I have been trying to grow native plants for the environmental benefits and to support insect and bird populations. You're website made it so easy to identify native flowers for my region. The growing tips are also much appreciated.

Product vs shipping

One packet of seeds arrived as ordered and the cost was reasonable. What seemed a little overpriced was $.5.00 for shipping that only cost $.71. I guess the extra goes to the employee who pulled the packet and put the label on the envelope.

DESCRIPTION

These vivid, yellow flowers almost glow in the sunlight, against their dark green foliage. They are easy to grow and make a fantastic choice for a prairie planting, a butterfly garden, or even as cut flowers.
This wildflower's common name of "tickseed" comes from the resemblance of the seeds to that particular bug; the genus name Coreopsis, derived from the Greek "koris," makes a similar reference to bedbugs. Hardiness and love of dry soil make the flowers in this family especially valuable to citizens of the state of Florida, who appointed Coreopsis as their official state wildflower in 1991.
