One of the best Flax for the garden, Linum narbonense (Blue Flax) is a compact, mound-forming, semi-evergreen perennial with lance-shaped, dark green leaves and profuse azure blue, funnel-shaped flowers, 2 in. across (5 cm), over a long season.

Blooming for weeks in late spring to midsummer, the blossoms are borne in open clusters atop wiry stems.

Long-lived, drought tolerant, this Mediterranean blue flax is perfect garden borders, wildflower gardens and informal plantings.
