Hydrangea is a genus of more than 70 species of evergreen and deciduous shrubs and climbers. They are grown for their spectacular, large flowers, borne in spherical, umbrella-shaped or conical inflorescences. The colour of the flowers varies, depending on the soil pH. Hence, flowers are blue in acid soils, cream-coloured in neutral soils and pink or fuchsia in alkaline soils.
They grow in full sun or part shade, in moist but well-drained, humus-rich soils.
Plant groups and in flowerpots.
Propagated by semi-woody cuttings from non flowering stems in spring and summer.
Most species require light pruning in winter and removal of overmature inflorescences.
Hydrangea paniculata "Burgundy Lace"
Deciduous shrub with conical inflorescences of red to fuchsia-coloured flowers in summer.
