Culver's Root

<< PREV Image 1 of 2 NEXT >>

Culver's root is a graceful perennial typically reaching 4-6' tall when in bloom. Slender flower spikes are densely packed with small white flowers that open from the top down in mid-summer. Butterflies and other pollinators visit the flowers for nectar. The tall stems provide good winter cover for all kinds of hibernating insect wildlife.

Benefits

  • Nectar source for butterflies and other pollinators
  • Seeds benefit game birds like quail or pheasant and finches
  • Old stems provide winter cover for beneficial insects
  • Blooms for 4 to 6 weeks
  • Good cut flower

Homeowner Growing and Maintenance Tips

Grow in moist, well-drained soil in full sun. Leaves will get crispy if the soil dries out. Tolerates light shade but requires support if grown in too much shade. Apply a balanced fertilizer two or three times during the season for best growth. Usually takes several years to become established in the garden. Leave the stems standing through winter to provide cover for beneficial insects.
