Hydrangea macrophylla
The mop-head and lace-caps of today descend from plants native to a small area in eastern Japan. They are long lived plants, easy to grow, thriving in shade, woodland gardens and near the coast, whilst they also thrive in shady spots. Their flowers range through green, white, pink, blue, red and purple. The flowers give a fine display from June until November. The traditional Hortensias (H. macrophylla), have two basic types of flowerheads.
- LACE-CAPS are usually flat with small flowers without petals in the centre and showy flowers with petals on the outside.
- MOP-HEADS have a ball of flowers at the end of the stems of the current seasons growth.
The Flower colour of Hydrangea macrophylla will vary with soil type and most will form round bushes between 1m and 3m tall.
Flower colour of Hydrangea macrophylla varieties
- The flowers of the pink Hydrangea macrophylla varieties will usually go blue in acid soils, but stay pink in alkaline soils. Blue flowers will only remain blue if the soil is acid and there is sufficient Aluminium Sulphate in the compost or soil in your garden, if the soil is alkaline the flowers will be pink. White varieties do not change colour with the soil.
- If you purchase a Hydrangea macrophylla with blue or pink in its name, on the nursery we have grown the blue ones in an acid compost and the pink ones in a neutral compost. The blue one will also have Aluminium Sulphate added to the compost. As soon as the Hydrangeas are re potted or planted in your garden the colour of the flowers may change depending upon the pH (acidity) of the soil.
- If you use a Peat free compost for blue varieties they will almost certainly come out pink.
- The technical explanation - the blue colour of Hydrangea macrophylla flowers is determined by the presence of an Anthrocynin Delphinidin 3 - Monoglucoside. The blue colour is caused by the binding of Aluminium Sulphate with the Anthrocynin. This happens under acid soil conditions.
*Please note the white and pale coloured flowered varieties will often burn if grown in full sun.
Pruning Hydrangea macrophylla varieties.
- Remove dead heads in spring (late March/early April), and thin out weak and dead stems. You can thin the brown stems to get larger flowers.
- Do not prune in the autumn as the old flowers give some frost protection to young shoots in early spring. The brown flower heads also look great in winter when covered in frost.
- If you need to shorten the plant always cut above a bud.
