About Perennial flax
Linum narbonense, commonly known as Narbonne Flax, is a low-maintenance perennial cherished for its delicate blue flowers that bloom profusely in spring and summer. Its slender, upright stems and glaucous foliage create an ethereal texture, making it perfect for rockeries, sunny borders, or Mediterranean and naturalistic garden styles.
Native range
Western Mediterranean region, especially southern France and the Iberian Peninsula.
Care tips
It requires full sun for optimal flowering and well-drained soils, preferably sandy or stony, as it is sensitive to waterlogging. Once established, it is quite drought-tolerant, so watering should be moderate, allowing the substrate to dry out completely between waterings. Avoid over-fertilization, as this can promote foliage growth at the expense of flowering.
