I've sown, I'm waiting for it to shoot. The packet contained very very few seeds. The shoot has to work, otherwise, there won't be enough to do it again a second time. What a shame.

Description
Linum narbonense 'Heavenly Blue' is a stunning perennial flax, native to the Mediterranean region. It displays abundant blooms in a beautifully intense shade of sky-blue. The flared flowers are fairly large, carried on slender stems that gently sway in the breeze. They form an erect clump of very soft, greyish green foliage. Ideal for sunny, dry areas of the garden, rock gardens and low-maintenance flower beds.
Linum narbonense occurs naturally on the dry coastal regions of the Mediterranean basin, from the south of France to Portugal and as far as Algeria. This woody-based perennial belongs to the Linaceae family. 'Heavenly Blue' is a beautiful variety, with its large, 4 cm blooms and unique colour. It forms a 40 cm tall clump of erect stems, which sway with the slightest breath of wind. They carry alternate, linear, grey-green leaves and masses of flowers from spring to autumn, depending on the climate. Each flared, cup-shaped bloom is a brilliant shade of sky blue, finely veined with indigo.
Flax is unrivalled for bringing a natural lightness and grace to formal bedding schemes. Although the plants are often short-lived, lasting only a few years, they self-seed easily. Sow perennial flax freely in rock gardens, wildflower meadows, borders and flower beds in light soil. It combines well with the sword-shaped leaves of Iris germanica, filling the space between the stems and taking over once they have finished flowering. It also performs well in pots. Its easy-going elegance suits plants with grey foliage such as Senecio cineraria, wormwood, officinal sage or Phlomis, which require the same growing conditions.

Planting and care
Perennial flax is generally direct sown in spring, in March-April. Sow the seeds 3 mm deep, in furrows spaced 30 cm apart, in loose, well-prepared soil. Water regularly, especially during dry spells. Germination generally takes 20-30 days. When the plants are strong enough to be handled, transplant them every 15 cm. 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. Sow in good quality sowing mix, at a temperature of 18-23°C, and cover with a fine layer of compost or vermiculite. Keep in a light place until germination. Transplant the young plants into pots in a frost-free place until they are ready to be moved outdoors the following spring. Perennial flax gives best results in light, well-drained, even poor, 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).
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 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.
The planting period indicated on our website applies to regions in USDA Zone 9a (East Coast and Midlands: Dublin, Wexford, Waterford, Kilkenny, Portlaoise). It will vary depending on where you live:
- On the west coast and in the north-west (Galway, Limerick, Sligo, Donegal, Westport), delay planting by 1 to 2 weeks in spring and bring it forward by 1 to 2 weeks in autumn compared to the dates given, preferably choosing periods without strong winds.
- In the inland hills and plateaus (Wicklow Mountains, Macgillycuddy’s Reeks, Connemara, Killarney), it is best to plant in spring (April–May) or autumn (September–October), avoiding periods of waterlogged soil in winter and strong winds, which pose the main risk to newly planted trees in these areas.
The flowering period indicated on our website applies to regions in USDA Zone 9a, such as the East Coast and Midlands, including Dublin, Wexford, Waterford, Kilkenny and Portlaoise.
This will vary depending on where you live:
- On the west coast and in the northwest (Galway, Limerick, Sligo, Donegal and Westport), it will be delayed by one to two weeks compared to the given dates, due to stronger Atlantic winds and less spring sunshine.
- In the inland hills and plateaus (the Wicklow Mountains, the Macgillycuddy's Reeks, Connemara and Killarney), flowering will be delayed by two to three weeks. Flowering mainly occurs between May and July, with the limiting factors being less frost and more of the excessive humidity, strong winds and lack of sunshine that are characteristic of these areas.
