hydrangea 'Libelle'

Grow in moist but well-drained soil in partial shade but sun is tolerated if soil remains reliably moist; acid soils with pH of less than 5.5 produce blue fertile flowers and soils with a pH of more than this produce pink fertile flowers. White ray florets are not affected by pH

Propagate by softwood cuttings in early summer or hardwood cuttings in winter

May be susceptible to aphids, capsid bug and hydrangea scale and vine weevil

May be susceptible to a leaf spot, grey moulds, powdery mildews and honey fungus
