Hydrangea Bretschneiderii or Shaggy Hydrangea
Shaggy hydrangea is a native of China China and Japan are lands where hydrangeas have been cultivated since ancient times and the first hydrangea to be brought from there to Europe was apparently also a cultivated plant. Shaggy hydrangea is taller than snowhill hydrangea; it grows to a height of 5 m (16 ft). It is of fairly spreading habit and takes up a space of as much as 6 square metres. The flattish inflorescence measures 10 to 15 cm (4 to 6 in) across. Theare dingy white; those on the edge are sterile and their petals are coloured reddish or slightly purplish. The flowering period is from August to October. Requirements as well as methods of propagation are the same as for the snowhill hydrangea.
Hydrangeas are grown not only as shrubs in the garden but also as pot plants. The latter are mostly forms of Hydrangea macrophylla or H. paniculata, which are nowadays bred and developed by well-known Dutch, Belgian, Swiss, French and German firms. The reason for this interest in hydrangeas is that they are one of the few shrubs which flower in late summer and autumn, and which are very decorative in containers, next to walls and on. When planted out in the open they are most effective as a loose border in front of dark conifers such as yew or evergreen shrubs (rhododendrons). Combinations of hydrangeas and are also very effective.
