Hydrangea paniculata Groundbreaker

Hydrangea paniculata Groundbreaker is a dwarf and very compact paniculate hydrangea. As a small ground cover, it is the first variety that does not exceed 40 cm in all directions! It is therefore ideal for borders, in pots and even as a centrepiece. From July to October, it produces white, conical inflorescences which mature to different shades of soft pink. Plant this robust hydrangea in moist, well-drained and humus-rich soil, in full sun or partial shade.

Hydrangea paniculata, also known as Mountain Hydrangea, is a species belonging to the hydrangea family native to deciduous forests in China and Japan and particularly hardy. The Groundbreaker variety has a dense and very compact habit. The main branches are erect, while the secondary branches are slightly arched. At maturity, this variety does not exceed 40 to 50 cm in all directions, with fairly rapid growth. In July, it blooms on the current year's branches with small, loose, very light-looking panicles. They consist mainly of fertile, single florets, evolving from a white hue to shades of soft pink in autumn, in sunny exposure. This gracefully curved inflorescence adorns the younger branches. It has well-branched vegetation, with branches covered in ovate and fairly light green leaves, measuring 5 to 10 cm long and 4 to 6 cm wide. They turn yellow in autumn before falling. Paniculate hydrangeas are less sensitive to late frosts as they generally bloom on the current year's growth.

Hydrangea paniculata distinguishes itself from its cousin, Hydrangea macrophylla, by its good tolerance to sun, sea spray, and relative drought. Planted in any good garden soil, preferably without too much limestone, Groundbreaker shows rapid growth. It is a very hardy variety that can be planted as a border, in mass plantings, or mixed with other plants, as well as in flower beds or pots. Cut its inflorescences to create beautiful bouquets. Pair it with small roses, heathers, and Deutzias, or low grasses like Stipa. On the terrace or balcony, it can live for many years with some fertiliser and regular watering.
