Sown in autumn 2025, they established well and produced magnificent flowers. The red flax only flowers until the summer heat arrives here in the South, but it is so beautiful!

Description
Linum grandiflorum 'Rubrum' or scarlet flax is a very easy-to-grow annual. This variety features satiny, scarlet red flowers with a darker red eye over delicate, silver-green foliage. It blooms all summer long, perfect for sunny borders, flower beds and rock gardens. Direct sow in well-drained and light soil.
Linum grandiflorum is a hardy annual that belongs to the Linaceae family, native to North Africa. It germinates, grow, flowers and sets seed before the heat of summer sets in. In more humid climates, it blooms all summer long, tirelessly. 'Rurum' forms a small, narrow clump of branched stems, quickly reaching 40 cm in height and 15 to 20 cm in width. Its leaves are small, thin and lanceolate, silver-green colour in colour. The flowers are flat and cup-shaped, measuring 2 to 3 cm in diameter; they are made up of 5 intense, scarlet red petals with a satin-like sheen and a darker red central halo. Although each flower only lasts one day, they are continually renewed from early summer to autumn. This plant will self-seed easily in light soil, however not always true to type.
Flowering flax is a sun-loving plant that is very resistant to drought. The seeds can be scattered directly in sunny flower beds or rock gardens, creating lovely informal combinations with Love-in-a-mist, Amni visnaga, Californian poppies, and other perennials such as Veronica hastata, Verbena bonariensis, and Centranthus ruber. It also mixes well with ornamental grasses such as Stipa pennata or Muhlenbergia capillaris.

Planting and care
Annual flowering flax is best direct sown in spring, or from late summer until early autumn. The seedlings are very hardy and will withstand harsh winter frosts. Sow the seeds 3 mm deep, in furrows spaced 30 cm apart, in loose, well-prepared soil. For plants that flower in winter and early spring, sow in late summer or early autumn and grow in pots in a cold greenhouse or veranda. Water sparingly until the weather warms up. Thin out the seedlings, keeping one every 10 to 15 cm. Flowering annual flax is hardy and resistant, it thrives in light, well-drained, or even stony soil and full sun.

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.
