Care of the Freelander Blue Prunella

Winner of the prestigious Fleuroselect Gold Medal in 2006, the Freelander Blue (Prunella grandiflora "Freelander Blue") is covered in soft lilac-blue flower spikes from May until October. This easy-to-grow perennial makes a good ground cover or edging plant, as well as an unusual container specimen. Unlike most perennials, Freelander Blue starts blooming its first year. It is hardy in U.S. Department of Agriculture plant hardiness zones 4 through 8.

Things You'll Need

  • Fertilizer
  • Organic mulch
  • Pruners

Instructions

    • 1

      Site Freelander Blue plants in full sun or partial shade for best flowering. The plants grow well in deeper shade but flowering is reduced.

    • 2

      Space your plants 6 inches apart for complete coverage the first year, or 10 to 12 inches apart for coverage by the end of the second year.

    • 3

      Feed prunellas once in the spring with a fertilizer formulated for flowering plants. Apply the fertilizer when new growth first appears. Don't overfeed, as this leads to excessive leaf growth at the expense of flowers.

    • 4

      Remove faded flowers to keep the plants blooming throughout the summer. Freelander Blue will flower from spring until frost if deadheaded regularly.

    • 5

      Water your plants often enough to keep the soil slightly moist. Prunellas prefer soil that's moist but well-drained, although they can tolerate light drought.

    • 6

      Spread 2 inches of organic mulch around the plants the first year to conserve water and discourage weeds. Once the plants have filled in, their leaves shade the soil so it's not necessary to spread mulch.

    • 7

      Clear away all old foliage and other debris in the fall after frost blackens the plants. This prevents diseases and insects from overwintering near your plants.
