Description

The late summer/fall garden is all about big and tall, and 'Gold Standard' Tickseed (Coreopsis tripteris ‘Gold Standard’) fits right in with towering stems covered with large bright yellow daisies for several months beginning in late summer. This cultivar was selected by the prestigious Mt. Cuba Center botanic garden of Delaware for its outstanding, strongly upright growth habit and extended bloom time. Vigorous and easy-to-grow Coreopsis 'Gold Standard' loves the sun and grows readily in a wide range of soils including clay. The plant attracts butterflies when blooming and seed-eating songbirds in the fall when the seed ripens. Planted with other tall, late-season blooming perennials such as Joe Pye Weed (Eupatorium), Maximilian's Sunflower (Helianthus), Prairie Switchgrass (Panicum) and Big Blue Stem Grass (Andropogon). These natives provide a stunning conclusion to the growing season and much needed nectar to many different pollinators.  

Planting & Care

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.
