Hydrangea
Hydrangeas are popular garden shrubs with delicate heads of flowers in shades of pink, white or blue and pretty autumn colour and leaf shape. The mophead and lace-cap hydrangeas are most well-known for their ability to change colour in different soils. One of the most interesting quirks of some hydrangeas is the ability of the flowers to change colour. This is not true of all hydrangeas, but most often seen in the mophead and lacecap cultivars of Hydrangea macrophylla. Colour changes can also be seen in flowers of others such as H. involucrata and H. serrata
