Its large flower clusters make the hydrangea (Hydrangea; sometimes misspelt Hydranchea) one of the most popular flowering garden plants. This flowering bush/shrub is perfect for a lush border or as broad hedge. Hydrangeas also are attention-grabbers in pots on a balcony or patio. The white, pink, red or blue flowers of the winter-hardy hydrangea bloom in the summer, change colours in autumn and are decorative long into the winter. The flowers of the hydrangea can also be used in bouquets of dried flowers. Would you like to buy Hydrangea plants? Find your favourite below and simply order online.
