Hydrangea serrata Klaveren - Mountain Hydrangea

Hydrangea macrophylla 'Klaveren', also known as Hydrangea serrata 'Klaveren', is a superb hybrid between H. serrata and H. macrophylla obtained by Pierre Michel Kerneur in France, in 1990. This hydrangea is quite hardy and forms a wide and flexible bush, adorned with large flat inflorescences whose large peripheral florets are open like flags in the wind. The colour of the inflorescences, pink with a blue heart, varies according to the nature of the soil. It will be more pink in neutral soil, and purple to blue in acidic soil. 

Originating from Japan and Korea, Hydrangea serrata are very hardy plants, belonging to the Hydrangeaceae family.

'Klaveren' comes from a lucky sowing of Hydrangea serrata 'Blue bird'. It forms a ramified, ample, and natural bush. After 3 years, it will reach a height of 1.4m (5ft) with a similar width, or more in the long term, depending on growing conditions. It is characterised by large, light green, dentate leaves, which turn brown over the season, especially when the plant is exposed to morning sun, and in autumn. Its flat, airy panicles, 15 to 20cm (6 to 8in) wide, blossom from early July and fade in lovely shades. The large sterile flowers, with very fringed edges, surround fertile flowers in the shape of buttons. The flowers will be pink depending on whether your soil is acidic or neutral to limestone. New inflorescences appear until September. This variety can be planted in fairly cold climates. It tolerates sun quite well, if it's not scorching. Hydrangeas are robust plants that can live at least 50 years.

'Klaveren' has the vigour of hybrid plants. Particularly appreciating moist and rich soils, as well as a semi-shaded exposure, this variety will elegantly impose its ample silhouette and its generous and nuanced flowering. Hydrangeas are well known for brightening up the north side of houses. This one will thrive in a north, east or non-scorching west exposure, in borders, hedges, or in a large pot on a terrace or near a doorway. Even though they fear limestone, hydrangeas are not strictly speaking ericaceous plants; they like rich soils. Combine them with magellanica fuchsias or annual impatiens, or plant spring-flowering bulbs in front of their round silhouette. Enjoy their sumptuous flowering in the garden or in the house for a long time.
