Tips For Growing Coreopsis (Tickseed)

Coreopsis (Tickseed) are long-blooming native wildflowers that are easy-to-grow and provide ample nectar for butterflies. They're resistant to browsing rabbits and deer. Coreopsis can be divided into two groups that have different growing requirements: Coreopsis grandiflora and Coreopsis verticiliata (Threadleaf Tickseed) cultivars and hybrids.

1. Coreopsis grandiflora types (Tickseed) - these cultivars are generally grown from seed and are a short-lived perennial (3 to 4 years).

Preferred growing conditions:

  • Needs sandy/gravely and sandy loam type soils. Avoid clay.
  • Does best with gravel mulches.
  • After their second growing season, only requires deep but infrequent watering. Too much water makes them floppy and shortens their lifespan.
  • Plant in full hot sun.
  • Adding just a few handfuls of compost and Yum Yum Mix in the planting hole is enough. Don't plant into a rich, highly-amended soil.

Special comments

  • Deadhead plants to prolong bloom. Leave a few seed pods on the plants to encourage re-seeding.

2. Coreopsis verticillata (Threadleaf tickseed) and hybrids - These are long-lived perennials that spread by rhizomes to form wide, dense growing clumps.

Preferred growing conditions:

  • These species grow in a wide range of soil types including clay. Avoid very alkaline soils as they may get chlorotic (yellow foliage) due to unavailability of iron and other trace minerals.
  • These plants don't need mulching except in hot climates.
  • These are moisture-loving perennials and do best in moderately moist soil conditions.
  • Plant in full sun areas.
  • They like compost-enriched soils at planting time.

Special comments

Threadleaf tickseed plants are often late to wake in spring from dormancy, so don't worry when other neighboring perennials wake up first.

Garden care for all types of Coreopsis:

  • Fertilize Coreopsis just once in fall with Yum Yum Mix and Planters II. In addition, for C. verticillata types, green sand is recommended for alkaline soils to correct or prevent chlorosis.
  • Plants can be divided in mid-spring when clumps die-out in the center or become too large for their place in the garden.
  • Leave all Coreopsis varieties standing over the winter and cut back to 1-2" inches above the soil in mid-spring when the plants begin to wake up.

    Comments about High Country Gardens Coreopsis grandiflora Sunray:

    Sunray was big and beautiful the first summer (2016) after planting. I have pea gravel mulch in my backyard because my 3 dogs don't dig in it. Not all plants do well with sun-baked hot rocks around them. Fortunately, Sunray performed beautifully with a lot of flowers. I deadheaded which prolonged bloom time. My dogs didn't bother it either. Great xeric plant!

        Comments about High Country Gardens Coreopsis grandiflora Sunray:

        Coreopsis is great for sunny spaces without a lot of water. The soil doesn't have to be the best either. No need to water frequently, usually normal rainfall is enough. I planted sunray years ago and still have wonderful bunches of flowers every year. Because they are low they are great in the front of my garden.

        Q & A

        Suggested Companion Plants:

        USDA Hardiness Planting Zones

        To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.

        • If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
        • If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).
