Hoary Skullcap

Scutellaria incana

Hoary Skullcap, also known as Downy Skullcap, features dense clusters of hooded, deep blue flowers that are a favorite among bees and butterflies. The plant stands out with its soft, gray-green foliage that provides a beautiful contrast in perennial borders and native plant gardens. This skullcap variety thrives in full sun to partial shade and prefers well-drained soils. It is particularly effective in naturalized settings or as part of a pollinator garden, where its midsummer blooms offer vital nectar sources during the hot months.

Maintenance Tips

  • Deadheading spent flowers may encourage a second bloom and prevent self-seeding.
  • Divide clumps in spring every 3-4 years to rejuvenate growth and manage spread.
  • Allow natural seeding in casual garden areas or remove seedlings to maintain design in formal settings.
