St. John's Wort

Availability: Out of stock

Large, cheery yellow blooms cover the tough, low-growing subshrub known as creeping St. John's Wort plant (Hypericum calycinum). Now, this isn't the same variety as the one you see in health food stores; but rather a durable landscape asset that delivers bright yellow blooms up to three inches wide with a fluffy "pom pom" of long, bushy stamens and reddish anthers sparkle in sunlight.

The main flush of blooms occurs in early summer, with sporadic reblooming all season-long. Over the season, the spent blooms develop into showy berries...perfect to include in your autumnal cut flower arrangements.

Planting and Application:

Glossy, oval leaves add a symmetrical precise look to these hard-working plants and remain evergreen in warm winters. Groundcover St. John's Wort spreads by underground stolons to suppress weeds on bare ground.

  • Give this groundcover room to spread to the largest width listed on the Plant Highlights. In optimal conditions, it may perform "too well" and our Plant Sentry Trade; software may block shipment into certain locations with regulations in place; type in your Zip Code to check.
  • Where we can ship this beautiful St. John's Wort becomes a lively resource to decorate bare ground in filtered sun under trees. It's tolerant of many conditions, but does flower best in full sun.
  • Use several to decorate a Rock Garden with a drape of happy color. It easily softens the base of your specimen boulders.
  • Add to a slope planting to help control erosion. Partner with drifts of colorful Sumac shrubs and anchor with a cascading planting pattern of clustered shrubs for a valuable garden feature.
  • Creeping St. John's Wort is also known as Aaron's Beard. Even beginning gardeners can have success with these charming, ground-hugging shrubs.

#ProPlantTips for Care: 

Plant 18 inches apart in well-drained soil and full sun for best flowering display. St. John's Wort plant care does include partial shade, but make sure it will receive at least four hours of sunlight a day.

  • Tuck symbiotic Nature Hills Root Booster in the planting hole for life-long support. Get more expert planting tips from our Horticulture Staff.
  • Over time, they will develop moderate resistance to periodic drought. However, our team does recommend that you apply water as needed during hot, dry weather.
  • Watch for the foliage to develop purple tones if the nights in your area stay cool enough. In early spring, you can prune off any winter damage as needed.
