Description
The Hydrangea paniculata Petite® Flori, also known as Paniculate Hydrangea 'Coussine', is a compact cultivar designed for terraces, small gardens, and the front of borders. Its flowering begins very early, from late May-June, continues throughout the summer, and evolves from white to pink and then to a deep red. The panicles of flowers are borne on robust stems tinged with red. Its small size allows for easy cultivation in pots as well as in the ground and the bush shows excellent hardiness.
Hydrangea paniculata belongs to the Hydrangeaceae family. The botanical species is native to East Asia (China, Japan, Korea, the Kuril Islands, and Sakhalin) where it grows on woodland edges and cool slopes. Horticultural synonyms for the cultivar: Hydrangea paniculata ‘Coussine’, ‘Petite Flori’ (Petite® series).
‘Coussine’ (Petite® Flori) is a French selection by Jacques Couturieux in Moyenmoutier in the Vosges, introduced to the market in 2022. The Petite® series is distributed notably by P.W. Captein. The growth of this bush is rapid in the first year then moderate; the habit is bushy and upright; it reaches approximately 80 cm in height and 60 cm in width within two seasons. Allow for 60–80 cm in a pot. The foliage, deciduous, is formed of opposite, ovate to lanceolate, dark green, finely dentate leaves; the young shoots are brown-red in colour and become grey-brown with age. The conical panicles combine small fertile flowers with large decorative sterile florets; they open white then take on pink tones and finally deeper reds late in the season. The flowering, on the current year's wood, lasts from late May/June to September. The foliage of this hydrangea is deciduous: it turns yellow in autumn before falling. This cultivar is hardy down to -25°C.
Plant this Petite® Flori hydrangea in a deep pot (30–40 cm) to decorate your balcony, or at the front of a shrub border; give it morning sun or partial shade, water regularly in summer and prune hard in late winter. It pairs well with low-growing ornamental grasses like Pennisetum alopecuroides ‘Hameln’, a compact Japanese spirea 'Little Princess', and other dwarf paniculate hydrangeas: Hydrangea paniculata ‘Bobo’, PETITE® Star (‘Coustar02’) or PETITE® Cherry (‘Couharie’), with compatible sizes. Its small stature allows it to be adopted without hesitation in a small town garden.

Planting and care
Hydrangea paniculata Petite Flori (Coussine) is not very demanding regarding soil type, as long as it is not too heavy, not too chalky, and rather moist. It requires a sunny but not scorching, or partially shaded position. When planting, set it in deeply worked soil. A good base fertiliser (horn or dried blood) will encourage the establishment of your young plant and nourish it without risk of scorching. If your soil tends to be dry, mix plenty of compost into the soil, mulch, and create a surface watering basin.
In late summer, we advise you not to cut the dry panicles, as they will protect the terminal shoots of the branches in winter.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
