Growth Stages

1

Seed to Seedling

10-14 days

Tiny seedlings emerge with fine, thread-like foliage. Plants are delicate and very small initially.

Keep soil consistently moist but not waterlogged. Provide bright light. Thin seedlings to 12 inches apart once they have true leaves.

2

Vegetative Growth

3-4 weeks

Compact, bushy mounding forms with fine, feathery foliage that remains 12-18 inches tall. Foliage is abundant and finely textured.

Water sparingly; drought conditions promote stronger, more compact growth. Avoid over-fertilizing. Pinch back growing tips when young to encourage bushiness if desired.

3

Flowering

8-12 weeks (or until frost)

Abundant daisy-like flowers appear with mahogany-red petals and golden-yellow centers. Blooms cover the plant profusely.

Deadhead spent flowers regularly to encourage continuous blooming. Water only during prolonged drought. Avoid high-nitrogen fertilizer which reduces flowering.

4

Peak Bloom & Self-Seeding

Continues until fall frost

Plant reaches maximum flower production. Seeds develop in spent flower centers if flowers are not all deadheaded.

Allow some flowers to remain if you want self-seeding for next year. Collect seed pods in late summer for controlled seed saving.

5

End of Season

Until first hard frost

Plant declines as temperatures drop and frost approaches. Foliage may turn bronze or burgundy before dying back.

Allow plant to die naturally in cold zones. In mild climates (zones 8-10), plant may persist into winter. Leave dried seed heads for wildlife.

Common Pests

  • Increase air circulation; spray with water; use insecticidal soap if severe. Drought-stressed plants are more susceptible.

  • Spray with strong water jet; use neem oil or insecticidal soap. Encourage beneficial insects like ladybugs.

  • Avoid overhead watering; ensure good air circulation. Apply sulfur or baking soda spray if needed. Plant is generally resistant when not stressed.

  • Hand-pick in early morning; use pheromone traps away from plants; apply neem oil for heavy infestations.

Harvest Tips

This is an ornamental flower grown for display rather than harvest. Deadhead spent blooms regularly to extend flowering season. For seeds: allow some late-season flowers to dry on the plant in late summer/early fall, then collect seed pods and store in a cool, dry location. Seeds can be sown again next year.

Fun Facts

  • 🌱 The genus name 'Coreopsis' comes from Greek words meaning 'bug' (koris) and 'appearance' (opsis), referring to the seed's resemblance to a tick or small insect.
  • 🌱 'Mahogany Midget' was specifically bred to be a compact, container-friendly version of the larger Plains Coreopsis species, making it ideal for small gardens and mixed borders.
  • 🌱 Plains Coreopsis is the state flower of Nebraska and has been used by Native Americans for centuries; the flowers produce a reddish dye when processed, which is reflected in the species name 'tinctoria' (meaning 'used for dyeing').
