About Perennial flax
Linum perenne, commonly known as perennial flax, is a delicate flowering herbaceous plant native to Europe. It produces abundant sky-blue flowers that last only one day but are continuously renewed throughout spring and summer. It is ideal for rock gardens, border fronts, or as part of a naturalistic garden, adding a sense of lightness and movement.
Native range
Europe and temperate Asia
Care tips
It requires full sun for optimal flowering and prefers well-drained soils, preferably sandy or stony, as it is sensitive to waterlogging. Watering should be moderate; once established, it is quite drought-tolerant. Avoid over-fertilization, as it can promote leaf growth at the expense of flowering.
