Hydrangea serrata Bluebird (Lacecap Hydrangea)

A great old variety whose popularity has rightly endured, gorgeous flattened lacecap heads of blue flowers start in June and the show continues through to September by which time the pointed green foliage begins to take on the Autumnal hues of dusky red, becoming deeper until the leaves fall in late autumn. a great little shrub that is well suited to smaller gardens and makes a great little flowering hedge.

Hydrangea serrata Bluebird 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.
