Switchgrass 'Northwind' (Panicum virgatum) - Ornamental grass - 11 cm pot - Height 25 cm

Yes, the upright Panic (Panicum virgatum) is fully hardy throughout France. It withstands temperatures down to -20°C without protection, and even lower according to some botanical sources. This hardiness is due to its origin: the great North American prairies, subject to harsh winters and scorching summers. You can therefore leave it in the ground all year round without fear of frost. In spring, it regrows vigorously from the crown, and the clump increases in size year after year.

The Panic erect 'Northwind' is a full-sun grass: it needs at least 6 hours of 'direct sunlight per day to develop its characteristic upright and compact habit. In 'shade or partial shade, the stems tend to flop and the plant loses its architectural appeal. Therefore, choose a south, southeast or southwest exposure, in an open space. In poor and sunny soil, it is often more beautiful and vigorous than in rich and shaded soil.

The Panic erect 'Northwind' lends itself to many combinations in naturalistic borders and prairie-style gardens. Its light panicles and bluish foliage 'pair perfectly with bright yellow-petaled Rudbeckia, pink or mauve Echinacea, and delicate mauve-flowered Scabiosa. It also pairs beautifully with Pennisetum, Agastache, or ornamental salvias to create colorful plant displays that attract pollinators. Its verticality contrasts elegantly with the rounded, spreading forms of prairie perennials, adding rhythm and structure to the 'overall arrangement.

At maturity, the Panic érigé 'Northwind' (Panicum virgatum) generally reaches a height of 1.20 to 1.80 m, including the flower stalks, with a clump diameter of 60 to 90 cm. It is one of the most upright varieties of the genus, with a strictly erect habit that does not flop over with the years. Growth is rapid: in optimal conditions of full sun and well-drained soil, the clump quickly gains volume from the second season. The plants delivered in 11 cm pots, at a height of 15-25 cm, will therefore establish themselves very quickly in your garden.

Absolutely: Panic 'Northwind' is 'one of the grasses best suited to dry gardens and poor soils. Native to the North American continental prairies, it is naturally selected to survive prolonged droughts and infertile, sandy, or loamy soils. Once established (usually after the first season), it requires virtually no additional watering, even in the height of summer. 'It is therefore a wise choice for gardeners seeking a water- and maintenance-efficient border, in keeping with the principles of sustainable gardening.

The upright Panic 'Northwind' s'should be cut back only once a year, in late 'winter or early spring, generally between late February and early March depending on the region. Cut the entire clump back to about 10 to 15 cm above the ground, using 'a pair of 'secateurs or 'garden shears. Avoid pruning in autumn at all costs: the golden flower spikes and tawny foliage of the upright Panic provide remarkable winter decorative appeal, and the hollow stems offer valuable shelter for beneficial insects. After spring pruning, the clump regrows quickly and regains its height within a few weeks.

No, the Panic 'Northwind' g'rass is not an invasive grass: it grows in well-defined clumps that 'expand very gradually over the years, without aggressive stolons or rhizomes. Unlike some grasses that quickly colonize the garden, it remains well-behaved and predictable. It may occasionally self-seed slightly, but its seedlings are easily identifiable and removable. It 'is therefore a grass that 'can be confidently incorporated into a mixed border, without worrying about losing control of the planting.
