Hydrangea

Hydrangea macrophylla ( syn. H. hortensis)

Other species are also grown in cooler climates. This page deals with Hydrangea macrophylla, the main type grown in Queensland.

These are classic shrubs for old-fashioned gardens, but whether the average gardener in subtropical SE Qld can supply the cool and moist conditions required for them to thrive in these days of water restrictions, global warming and tiny gardens infested with tree roots and surrounded by brick and concrete, is another matter. Has anyone had success with them as container subjects over the long term?

Hydrangeas are famous for their ability to change colour. While alkaline soils will increase the tendancy to pink, acid soils will increase the tendancy to blue. Check out the links for more information on this and other aspects of hydrangea culture.
