Hydrangeas come in all shapes and sizes. The most well known is probably the Macrophylla with it's striking blue, pink and even white mophead flowers. Did you know, Hydrangeas have the nickname the "Change Rose" because of their ability, in some species, to change flower colour depending on the pH Level of the soil they grow in.
Originally from Asia and the Americas there are now over 70 species of Hydrangea in the world. There is even an Island in the Azores named "blue island" due to the vast quantity of blue Hydrangeas growing there. Plant Hydrangeas in your garden to attract bees, butterflies, moths and other useful pollinators to your garden.

Also known as bigleaf hydrangea, French hydrangea, lacecap hydrangea, mophead hydrangea, penny mac and hortensia. Hydrangea macrophylla should be pruned in late winter or early spring. Leave the dried flower heads on the plant over winter to protect the new developing buds from frost, then deadhead them in spring, cutting back to the first pair of healthy buds below the flowerhead. If buds do get damaged by frost, cut the stems back to a strong pair of healthy buds. Cut back one or two of the older flowered stems to their base to promote new growth.
Grow in moist but well-drained moderately fertile, humus-rich soil in full sun or partial shade. Hydrangea paniculata 'Wim's Red' produces honey scented flowers. The flower heads once cut & dried make great flower arrangements.

How to grow a hydrangeas
Hydrangeas are hardy and can be grown outdoors wherever the winter temperature stays roughly above -15ºC (5ºF). They enjoy moist, well-drained soil and do best with shelter from the hot afternoon sun. This makes them ideal choices for shady gardens, and their dramatic round flowerheads look stunning in mid and late summer. Water hydrangeas regularly, especially in dry periods, and mulch with compost or other organic material in spring or autumn.
