Centranthus ruber and Centranthus Albus
Centranthus ruber Coccineus, Albus
Red valerian, Jupiter's beard, Spur valerian
The entire package arrived in excellent condition. I tried the plastic-free delivery and I think I'm going to stick with it: the young plants are better secured than in the buckets, and the height of the bag prevents soil from spilling out. PERFECT.

Description
This duo of valerians is available at a great price. It comprises Centranthus ruber and C. ruber 'Albus'. These deciduous perennials are remarkable not only for the duration of their flowering in clusters of pink-red and white flowers, but also for their ease of cultivation in any well-drained soil. They quickly form beautiful clumps measuring 60cm (24in) to 1m (3ft) in height that bring a lot of charm to rockeries and flower beds. Adapted to dry soils, they can withstand temperatures as low as -15°C (5°F). Spontaneous sowings are frequent.
This duo consists of:
1x Centranthus ruber: this wild plant is known for its pink flowers, tending towards red, which add colour to the garden. It reaches a height of about 70cm (28in) to 1m (3ft), and thrives particularly well in limestone soil. The flowering period extends from May to September.
1 x Centranthus ruber 'Albus': a variety with white flowers. More compact, this variety measures between 60 and 80cm (24 and 32in) in height. It is more suitable for small spaces.
This duo of valerians can be planted in flower beds, rockeries, above walls, or on banks. Place the taller Centranthus ruber at the back and the more compact C. ruber 'Albus' at the front. Use 5 to 6 plants per square metre for a beautiful mass effect. The spacing between two plants should be at least 40 to 50cm (16 to 20in) for optimal growth.
The red valerian and its white form go perfectly with plants such as lavenders in dry soil. For a contrast of colours, consider perennial geraniums, especially the variety 'Rozanne' which offers a beautiful and long-lasting blue flowering. Ornamental grasses such as Pennisetum alopecuroides 'Hameln' bring a different texture. Bush roses, like 'Bonica', can be interesting to vary the heights and colours in a flower bed.

Planting and care
Centranthus ruber is perfectly resistant to cold, summer drought, and sea spray. It is not demanding on the nature of the soil. It tolerates a wide range of soils, if properly drained, ranging from rocky and stony to clayey and compact. However, it prefers limestone and poor soils. Choose a sunny or partially shaded exposure: the plant tends to bend to seek light. It self-seeds spontaneously among trees and bushes without being invasive, and sometimes in unexpected places like old walls or even partially tarred banks.

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).
The flowering period indicated on our website applies to countries and regions located in USDA zone 8 (France, the United Kingdom, Ireland, the Netherlands, etc.)
It will vary according to where you live:- In zones 9 to 10 (Italy, Spain, Greece, etc.), flowering will occur about 2 to 4 weeks earlier.
- In zones 6 to 7 (Germany, Poland, Slovenia, and lower mountainous regions), flowering will be delayed by 2 to 3 weeks.
- In zone 5 (Central Europe, Scandinavia), blooming will be delayed by 3 to 5 weeks.
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The planting period indicated on our website applies to countries and regions located in USDA zone 8 (France, United Kingdom, Ireland, Netherlands).
It will vary according to where you live:
- In Mediterranean zones (Marseille, Madrid, Milan, etc.), autumn and winter are the best planting periods.
- In continental zones (Strasbourg, Munich, Vienna, etc.), delay planting by 2 to 3 weeks in spring and bring it forward by 2 to 4 weeks in autumn.
- In mountainous regions (the Alps, Pyrenees, Carpathians, etc.), it is best to plant in late spring (May-June) or late summer (August-September).
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
