Whatcom Counties go-to summer flower stuns in vivid tropical reds, pumpkin orange, and gold.
Coreopsis is a native American prairie and woodland plant. They are well known for their toughness and colorful blooms. The coreopsis varieties we grow here at Van Wingerden Greenhouses are low maintenance, drought tolerant, and long blooming. We have found the Coreopsis plants are workhorses in your colorful and sunny flower border. Their common name, “tickseed,” is supposedly for the seeds’ resemblance to ticks. That doesn’t stop the birds from devouring them if you leave the seed heads on during the winter. Goldfinches, in particular, enjoy Coreopsis seeds.
All the coreopsis we grow are clump-forming, holding their daisy-like flowers on tall stems, above the foliage. You probably have seen these flowers before and noticed the large variety among Coreopsis species. Coreopsis grandiflora has bright yellow flowers on tall stems that bloom all summer. Coreopsis rosea has finely textured leaves and pink daisy-like flowers with yellow centers. The increasingly popular Coreopsis verticillata is called the threadleaf coreopsis because of its extremely fine and ferny leaves. We grow both the Verticillata and a new hardy breed called Hybrida.

With most other plants, keeping them alive can get a little tricky. Not with COREOPSIS, these flowers are quite hassle free. Below are a few highlights on how to make your COREOPSIS thrive:
LIGHT: It is a heat tolerant plant. Coreopsis will bloom best in full sun, but it can also be successfully grown in partial shade. The plants may stretch in partial shade, but they will adapt. In areas with intense dry, heat, coreopsis may even prefer some afternoon shade.
SOIL: The coreopsis varieties we grow are very easy to grow and are not particular about soil quality or soil pH. An addition of compost will help with both clay and sandy soils common here in Whatcom County.
PLANTING: Plant in spring, spacing them 14 – 16″ (36 – 41cm) apart. Dig a hole 2x the size to the diameter of the container or pot in which the plant is. Remove the plant from the container and place it in the hole so the top of the root ball is level with the soil surface. Mix compost, slow release fertilizer and the dirt you removed from the hole and carefully fill in around the root ball. Firm the soil gently. Water in thoroughly.
WATER: Coreopsis is drought tolerant, so avoid over watering or dripline irrigation. A moderate amount of water should be provided.
FERTILIZER: Provide balanced and complete fertilizer mix. Once a month is enough. A rose food or all purpose organic fertilizer works well. We recommend and use Down to Earth brand fertilizer
MISCELLANEOUS: Hardiness zone ranges from 4a-9b. We are in 8a here in Whatcom county.
Deadheading will keep the plants blooming throughout the summer. You may prefer to shear the plants, once the first flush of flowers fade. They will fill in quickly.
For the winter, try pulling them out of the ground and putting them in containers, if you live in a place that has strong northerly winds.
Place in a cool bright location. Little or no water is required, maybe a few dribbles once in a month to keep the roots alive.
COREOPSIS is a hardy durable plant for your yard. It’s a perennial you can plant and count on its performance year after year. This vigorous grower will never fail to meet your expectations.
Although they are rugged plants, they don’t tend to live more than 3 to 5 years. A decrease in flowering is a signal it is time to divide the plants or replenish from your favorite local garden center!
