Purple Coneflower Instructions

PLANTING

CHOOSING AND PREPARING A PLANTING SITE

  • Coneflowers prefer well-drained soil and full sun for best bloom. Choose a location where the coneflowers won’t get shaded out nor shade out others.
  • They may reach between 2 and 4 feet in height, depending on variety.
  • Coneflowers are very tolerant of poor soil conditions, but they perform best in soil that’s rich so mix in organic matter if needed.
  • Coneflowers are drought tolerant.
  • Loosen the soil in your garden using a garden fork or tiller to 12 to 15 inches deep, then mix in a 2- to 4-inch layer of compost. 

WHEN TO PLANT CONEFLOWERS

  • More commonly, coneflowers are bought as small plants with blooms already on the way. These should be planted in spring or early summer.
  • Coneflowers can be started from seed in spring indoors (about a month before the last spring frost date) or outdoors (when the soil temperature has reached at least 65°F/18°C).
    • Note: Coneflowers started from seed may take 2 to 3 years before producing blooms.
    • Better yet, don’t cut back coneflower plants and they’ll self-seed successfully!
  • If dividing or transplanting coneflowers, do so in the spring or fall.

HOW TO PLANT CONEFLOWERS

  • Plant coneflowers about 1 to 3 feet apart, depending on the mature size of the variety.
  • If you are moving a potted plant into the ground, dig a hole about twice the pot’s diameter and carefully place the plant in the soil. Bury the plant to the top of the root ball, but make sure the root ball is level with the soil surface. Water it thoroughly.
