Hydrangea macrophylla 'Black Steel Zambia' (Black Steel Series)

black steel hydrangea

Pot size 5 litre pot
5 litre pot
  • Position: partial shade
  • Soil: moist, well-drained, moderately fertile, humus-rich soil
  • Rate of growth: fast-growing
  • Flowering period: June to October
  • Hardiness: fully hardy

    A recently introduced cultivar that produces the much-loved flower clusters throughout summer and autumn, but these are carried on lustrous, near-black stems. This gives the plant a unique and attractive twist. The flower colour can vary when grown on acidic soils, but generally the deep pink flowers of 'Zambia' appear a lime green colour when they are first emerging, and both the young and more mature flowers contrast really well with its steely coloured stems. A very welcome addition to the family.

  • Garden care: Leave the old flower heads in place through the winter. As the new shoots start to emerge in spring cut back a third to a quarter of the previous seasons flowering stems to the base and cut back the remaining flower heads to the first pair of buds.
