Shrubby St. John's Wort

Hypericum prolificum

Shrubby St. John's Wort is a small, dense shrub that typically grows 2 to 4 feet tall and wide. It boasts a profusion of bright yellow, star-shaped flowers throughout the summer, which are highly attractive to pollinators such as bees and butterflies. The flowers are followed by small, woody seed capsules that provide visual interest in the fall and winter. The shrub's bark is another appealing feature, exfoliating in thin layers to reveal a rich, textured surface. Shrubby St. John's Wort thrives in full sun to partial shade and prefers well-drained soils. It is particularly valued for its drought tolerance and low maintenance needs, making it suitable for xeriscaping, pollinator gardens, and foundation plantings.

Ecological Benefits

Maintenance Tips

  • Drought-tolerant once established; water moderately until then, especially in very dry conditions.
  • Prune in late winter or early spring to maintain shape and promote healthy growth. Deadheading spent flowers may encourage reblooming.
  • Prefers well-drained soil but can tolerate a range of soil conditions, including poor soils.
  • Apply a layer of mulch to conserve soil moisture and suppress weeds.
  • Monitor for pests and diseases, though it is generally pest-resistant and low-maintenance.
