Hydrangea Mariesii perfecta (Hydrangea macrophylla Mariesii Perfecta) (Hydrangea Blue Wave) Lacecap Hydrangea

An old fashioned variety that is a favourite with gardeners, Hydrangea mariesii Perfecta has flattened lacecap flowers of rich blue arranged delicately around the centre of the flower. The large serrated leaves are deep green, setting the flowers off nicely. This is an excellent back of border shrub and a brilliant informal hedging plant, easy, tough and robust.

Hydrangea mariesii is easy to grow in sun or partial shade, they prefer a rich moisture retaining soil that doesnt dry out too much in Summer, thinnner and lighter soils would benefit from a good amount of organic matter being well mixed in the hole at planting time and these glorious shrubs enjoy a good mulch being applied during Spring to get the best from them, this is especially the case for younger plants. Prune the old flower heads off in spring, reducing the plants back to a strong bud and removing any weak or crossing stems. We recommend adding Rootgrow when planting all Hydrangeas to give them the best start.

Blue Flowered Hydrangea information – the colour of the flowers depends on you soil pH, soil needs to be acidic (pH less than 7) for them to be blue:

Soil pH above 7 (alkaline) Blue Hydrangea cultivars will have pink flowers

Soil pH at 7 (neutral) Blue Hydrangeas will have pink/lilac/mauve flowers

Soil pH under 7 (acidic) Blue Hydrangeas will have blue flowers.

You can add blueing powder (aluminium salts) to alkaline soils which may help although planting white or pink varieties may be a better solution.
