  • Winner of Best New Plant Variety in the 'Hardy Nursery Stock' category at The Grower of the Year Awards 2014
  • Grow the most colourful hydrangea ever!
  • Flowers constantly change colours
This stunning variety is one of the most eye catching hydrangeas available. The rounded flower heads are formed by dozens of red florets with blue centres, each petal tipped with an extraordinary shade of lime green. Found as a chance seedling, this incredible variety is repeat flowering producing a second flush of flowers later in the season. As with many varieties, Hydrangea macrophylla 'Glam Rock' produces slightly different colour tones depending on the soil pH. This robust, hardy shrub makes a superb addition to borders or large patio containers. Height and spread: 120cm (48").

Flowering Months
Water regularly until plants are fully established. Leave the faded hydrangea flower heads in place until the new buds swell in spring to protect the delicate buds from frost damage. Prune after flowering, reducing the stems to restrict their growth to the available space and to improve the shape of the plant. After pruning hydrangeas, apply a mulch of well rotted manure or compost around the base of the plant. Caution: Contact with hydrangea foliage may irritate the skin and eyes and all parts are harmful if eaten.
Hydrangea macrophylla prefers a sunny or semi shaded position, with shelter from cold, drying winds. Grow hydrangea plants in any rich fertile, moist soil. Improve the soil prior to planting by adding with plenty of well rotted manure or garden compost, ensuring that it is mixed in thoroughly and deeply. Alternatively plant hydrangea macrophylla in patio containers in soil based compost such as John Innes No. 3.
