Depending on the place you live, and on the variety you’re growing, Coreopsis either grows as a perennial or an annual.
Coreopsis planting is either in fall or in spring, but avoid times of frost and high temperatures.
Propagate it through crown division at the beginning of spring.
Sowing early in the season (April) under shelter or in a nursery, transplant to the ground when the last frost date has passed.
It’s possible to sow directly in the plot after this date (last frost) but the blooming will appear much later.
For an even earlier blooming, such as end of spring, sow directly in the plot in March with protection. A tunnel or cold frame are perfect.
Cut wilting flowers off as they die away to stimulate new blossoms.
Pull annual varieties out after they’ve given you new seeds to plant for next year. Lay the stems across the growing bed for mulch and fertilizer.
Water in case of strong heat wave or of extended drought.
This herbaceous plant native to North America exists both as an annual and as a perennial.
It grows to a bushy shape.
It often brightens flower beds and edges with its bright yellow flowers.
There are a few interesting Coreopsis varieties, for instance:
Coreopsis grandiflora is remarkable: it grows over 3 feet tall (1m). Its yellow flowers bloom from May to September.
Coreopsis lanceola is shorter, only 1½ feet tall (40-45 cm). Yellow flowers as well.
Coreopsis rosea has flowers that are an elegant pink hue.
To appeal to other senses, try Coreopsis tripteris that releases an anis-like fragrance.
Coreopsis verticillata is taller than the lanceolata, reaching 2 feet / 60 cm very quickly.
There are also a great many hybrid tickseed flowers with many different shapes and colors.
This is most often Coreopsis tinctoria which has a beautiful blooming during the entire summer. Flowers are yellow with a purple heart.
Stake taller stems to avoid having them break due to wind.
Divide clumps every 2-3 years.
