Description How to Grow More Info Delivery Reviews Video
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.

Partly good 2016-08-30

I ordered 2 of these. One came looking very robust and healthy. The other looked as if it had been partially eaten, with holed and ragged leaves and brown spots on some leaves. I planted them both straightaway in John Innes No.3. The damaged leaves on the poorly plant are falling off and I just hope it recovers. The other one is looking healthy and growing well, so part of the order was good, the other not so good.

Great 2015-11-07

Ordered this in April and it arrived mid May, planted it straight out, pleased to say it has thrived and has a bloom not dissimilar to the current picture, two new healthy shoots have emerged too.

Unusual and stunning 2015-07-22

Ordered in April and arrived in May. Planted it in a pot and waited. For some reason I thought it was going to be blue but it started with greenish flowers which are now turning pink, exactly like the photo. It is very unusual and stunning as it is so different from my other hydrangeas. Think it's great. Thank you.

fantastic 2015-05-16

Exquisite plant 2014-12-08

Simply Beautiful. Bright pinky-red flowers have gradually bloomed through out the summer. Very happy with this addition to my garden. As an amateur gardener, I am over the moon with this hardy shrub. When it arrived several months ago, it was very bare with only a few little branches growing. However it has really thrived and looks a totally different plant. So pleased with the hydrangea glam rock.
