Hydrangea macrophylla Onyx™ Peacock is a compact, bushy, deciduous shrub boasting large, blue, and purple mophead flowers. Blooming from early to late summer, the long-lasting blossoms are borne on sturdy black stems and contrast nicely with the healthy foliage of rounded, serrated, dark green leaves. This bigleaf hydrangea is perfect for foundation plantings, mixed borders, perennial gardens, and patio containers. A great choice for flower arrangements too!

  • Grows up to 50 in. tall (125 cm) and 20 in. wide (50 cm)
  • A sun to part shade lover, it is best grown in rich, medium moisture, well-drained soils. Tolerant of sun if the soil remains moist.
  • Perfect from foundation plantings to container plantings. Massed in a sheltered location or as an accent plant.
  • No serious pest or disease issues. Watch for botrytis blight, bacterial wilt, leaf spot, and mildew.
  • Remove spent flowers to promote new blooms.
  • To change the color of your Hydrangea, add aluminum sulfate to the soil to make the flowers bluer or add lime to the soil to make them pinker. Treatment should occur ahead of time (late fall or early spring)
  • This beautiful deciduous shrub should be pruned after flowering by cutting back the stems to a pair of healthy buds. Prune out weak or winter-damaged stems in early spring.
  • Propagate by softwood cuttings in early summer or hardwood cuttings in winter.
  • Hydrangea macrophylla species is native to Japan. It is reported from seaside habitats as well as mountains in Japan, from Honshu southwards. This species has naturalized in China, New Zealand, and the Americas.
  • May cause mild stomach upset if ingested, and contact with foliage may aggravate skin allergies. Wear gloves and other protective equipment when handling.
