About this plant
This is a handsome hydrangea which has large broadly oval leaves that taper and which tend to curve down at their tip. It has spreading branches and takes up plenty of room. The handsome foliage is set off, in July and August with magnificent lacecap flowers, The ray flowers are porcelain blue in acid soils with pinkish white florets, or misty purple in alkaline soil. The little clustered fertile flowers that make a central dome are coloured violet. In autumn the flowers take on reddish hues, so the decorative season for this shrub is prolonged. The foliage and colour combination is superb. It is a vigorous and hearty plant. This will stand around 3m (10ft) in height with a 4.5m (15ft) spread.

Water to keep the soil moist
For best results, this plant needs soil that is always moist. Water deeply and regularly as soon as soil appears dry. Even for established plants in the ground, a dry week can cause problems with some soils. Check plants in pots more often, especially in hot weather. Or install an automatic irrigation system which will do the hard work for you, even when you are away on holiday.
Without regular watering some plants never fully regain their beauty.
Summer
Summer - early · Outdoors
Apply slow release fertiliser
Apply a slow release fertiliser which is spread around the root area of the plants soon after they have come into growth. (Or apply a liquid feed at regular intervals throughout the growing season.)
This is a simple way to provide a nutrient boost as a single annual procedure.
Planting & general
Outdoor planting · Planting
Add root growth stimulant to the planting hole
Mycorrhizal fungi helps roots establish quickly, so they absorb water and nutrients more efficiently. It comes as a powder, granule or gel. Add to the planting hole or container, and to the plant's rootball before planting in the hole. For "bareroot" plants use a gel.
