No problem with recovery. The young plant was a bit thin this year, but still managed to flower. Perhaps it's a bit too shaded.

Description

Centranthus ruber Kempenhof, or Pink Valerian, is a perennial herbaceous, clump-forming plant. From July to September its upright stems bear beautiful fragrant, pink flowers in compact clusters. These funnel-shaped flowers are 1 to 2 cm (0 to 1in) long.

Pink Valerian has deciduous foliage, composed of lanceolate (lance-shaped), entire, and slightly toothed, dark green leaves, 5 to 8 cm (2 to 3in) long. The lower leaves are petiolate (attached to the stem by short stalks), while the upper leaves are sessile (directly attached to the stem). At maturity, Centranthus Kempenhof can reach a height of 80 cm (32in).

It is a very hardy perennial originally from the Mediterranean which attracts bees and other pollinators and self-seeds. You can grow it in flowerbeds, on dry slopes, or in rock gardens. It is sometimes used to decorate old walls and can grow in cracks or gaps everywhere.

Planting and care

Valerian likes the sun, it can tolerate partial shade but will not flower as well. It is drought-resistant. Plant it in well-drained, poor and not too fertile soil. Regularly remove faded flowers to prevent self-seeding. This will prevent the plant from becoming invasive and promote reblooming. Renew the plants every 2 to 3 years. Valerian is resistant to diseases and parasites.
