Wild Hydrangea

Hydrangea arborescens

Wild Hydrangea, also called Smooth Hydrangea, is a versatile and hardy native shrub that typically grows 3 to 5 feet tall and wide, with a rounded habit. The shrub produces large, rounded flower heads consisting of numerous small, creamy white blooms from early to mid-summer. These flowers are not only aesthetically pleasing but also attract and support butterflies and bees. After the flowering period, the blooms may turn a pale green, adding further interest throughout the season. Wild hydrangea thrives in partial shade, preferring moist, well-drained soils rich in organic matter. It is an excellent choice for underplanting larger trees, filling out shaded borders, or creating naturalized drifts along woodland edges.

Ecological Benefits

Maintenance Tips

  • Prefers evenly moist soil; water regularly, especially during dry spells.
  • Prune in late winter or early spring to remove dead wood and encourage vigorous new growth. It blooms on new wood, so pruning will not affect flowering.
  • Thrives in rich, well-drained soil; amend with compost to improve soil structure and fertility.
  • Apply a layer of mulch to conserve soil moisture and suppress weeds.
  • Monitor for pests like aphids and diseases such as powdery mildew, managing as necessary to maintain plant health.
