Very pretty little perennial with very bright colours. Planted as soon as received in the shade, last September, it brightens up a less exposed part of the garden... A delight at the end of the season. Vine-plant in accordance with the photos and delivered without any problems. I recommend this website to everyone.

Description
Saxifrage cortusifolia 'Black Ruby' is a perennial of the undergrowth with chocolate-brown foliage. It blooms from September to November, with peculiar purple-pink flowers.
Â
This small plant produces a rosette of deciduous leaves, 20cm (8in) in diameter. They are lobed, toothed, rounded, shiny, 5 to 8cm (2 to 3in) long, and chocolate-brown in colour. At the end of summer, pyramidal panicles, 10cm (4in) long, offer pretty cup-shaped flowers with 4 upper petals and 2 longer lower petals. They are purple-pink, and measure 3 to 5cm (1 to 2in) in diameter. Lean in a little closer to enjoy their delicate scent.
'Black Ruby' thrives in light, humus-rich, moist and well-drained soil in semi-shade or full shade. Plant it in a shady rock garden, borders, or walls. It can also be planted in containers with campanulas or Veronica umbrosa.Â
Â
Â
NOTE: Attention! This is a delicate plant to be reserved for experienced gardeners. Plant 'Black Ruby' in any light and moist soil. This perennial does not tolerate heavy and wet soils 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).
