The Hydrangea has 80 or more species of deciduous and evergreen shrubs and climbers. They originated from woodland in East Asia, and North and South America. Bear this in mind when looking at the best place to plant them, as they will grow far better in similar conditions to that of their origin. They are mainly grown for their large, showy flowerheads but many have ornimental flaky, peeling bark, and attractive foliage with good Autumn colour. The flat, domed or conical flowerheads comprise corymbs or panicles of both tiny fertile flowers and larger sterile flowers with showy, petal-like sepals.
