Hypericum calycinum ‘Golden Rule’ (St. John’s Wort) is a small shrub noted for its colorful foliage. Arranged along procumbent stems, the oval leaves emerge soft orange and buttery-yellow before turning to chartreuse-green. Unlike other varieties, its foliage will not revert to dark green. In summer, bright yellow flowers, 2 in. wide (5 cm), adorned with a prominent tuft of bushy stamens and reddish anthers are on display, adding further charm to the shrub. A luminous groundcover for shady beds and borders.

  • Grows up to 12-18 in. tall (30-45 cm) and 12-24 in. wide (30-60 cm). Spreads by underground stems. May invade other plantings unless confined.
  • A full sun to part shade lover, this plant is easily grown in medium moisture, well-drained soils. Tolerates a wide range of soils but thrives in sandy soils. Best flower production occurs in full sun. Drought tolerant once established.
  • Low maintenance, this plant is also generally pest and disease free. Deer resistant and salt tolerant.
  • Perfect for rock gardens, border fronts, naturalized plantings or massed as a ground cover. Great on banks and slopes for erosion control or under trees where it competes well with shallow tree roots.
  • Clip or mow plants in late winter or early spring every 2-3 years to renew and promote new growth.
