How to grow Linum (Flax) Seeds
Linum, commonly known as flowering flax, is an easy-to-grow annual or perennial flower valued for its delicate blooms and natural, airy appearance. It grows best in full sun and light, well-drained soil. Sow linum seeds directly outdoors after the last frost, or start indoors 4–6 weeks earlier for earlier flowering. Cover seeds lightly with soil and keep the surface evenly moist during germination at around 16–21°C. Germination usually takes 10–20 days.
Once seedlings are established, thin or transplant plants to around 20–30 cm apart. Linum prefers open, sunny conditions and performs especially well in poor to moderately fertile soils with good drainage. Avoid overly rich soil, as this can encourage excessive leafy growth and fewer flowers.
Linum is particularly well suited to cottage gardens, wildflower planting, Mediterranean-style landscapes, and drought-tolerant gardens. Once established, it requires very little maintenance and tolerates dry conditions well. Its fine stems and soft blue, white, red, or pink flowers create a light, natural effect that mixes beautifully with other annuals and pollinator-friendly flowers.
For best results, water moderately during establishment, then reduce watering once plants are growing strongly. Deadheading can encourage additional flowering, although many varieties naturally continue blooming over a long season. Linum is excellent for sunny borders, meadow planting, gravel gardens, containers, and low-water landscapes, while also attracting bees and beneficial pollinators.
