Hydrangeas are back in vogue with their large and persistent flowerheads that appear later in the summer when many other garden shrubs are past their best. The almost everlasting flowers of mophead hydrangeas are very popular with floral artists. These are deciduous shrubs for garden borders where they look fantastic in a woodland setting and in larger groups if you are lucky enough to have space – or as a refreshingly alternative (and very beautiful) informal hedge.
Hydrangeas do best in deep rich soil with lots of organic matter worked in, and generous annual spring mulches, especially in thinner chalky soils as all Hydrangeas appreciate their ‘feet’ in cool and moist conditions. They are tough and hardy plants but can be caught by late spring frosts so try to avoid planting in frost pockets, or exposed East facing positions.
Mophead hydrangeas have large rounded flowerheads appearing from July onwards in colours of red, white and blue. (The blue flowered varieties will need hydrangea colourant (Aluminium sulphate) added if you grow them on alkaline soil otherwise the flowers will be pink). Cut back old flowering shoots after the flowers have faded – unless you want to keep the decorative flowerheads over winter, in which case they may be left until spring. Mophead Hydrangeas do very well by the sea also.
Hydrangea arborescens ‘Annabelle’ is a very hardy variety, the spectacular rounded heads of white flowers can be up to 30cm across appearing from July, and keeping their colour into late Autumn. ‘Annabelle’ will make an excellent informal hedge or use the plants to fill larger formal beds as an alternative to Roses.
The paniculata varieties are grown for their beautiful cone shaped flower heads that appear from late summer well into autumn, the spent flowerheads giving winter decoration. These also make a great informal hedge needing little more than an annual prune of the old flowering branches each spring to keep them tidy and ensure prolific flowering the following Autumn.
For informal hedges we recommend all our Hydrangea varieties are spaced at 2 plants per metre. We offer generous quantity discounts and free delivery on all orders over £50 (ex VAT).
