Blue Flax, which is also known as linum is a short lived perennial that is best sown outdoors as it does not transplant well. Pretty sky-blue flowers 2.5 cm (1″) across, are produced in large numbers on 25-30 cm (10-12″) tall plants with fine textured gray-green foliage. Some plants can reach 60 cm (2′) height. Linum self-seeds readily. Perennial reliably hardy to Zone 5, but can sometimes persist in Zone 4 with winter protection. Native to Europe and Asia, Blue Flax growes best on medium to light soils in full sun. Tends to root poorly in clay dominated soils which can lead to winter survival problems.
