Blue Flax (Linum lewisii) is one of the most recognizable wildflowers in northern Utah, and a favorite here at Cache Valley Native Plants. Blue Flax features attractive and interesting, spirally arranged foliage and a profusion of blue suacer-shaped flowers. Although these blooms only last for one day, the plant will put on a show of flowers from late spring to mid summer. After it is done flowering, small, round seedheads will remain on the plant until the end of summer. Although Flax usually only lives a few years, it generously reseeds itself and will maintain a constant presence in the garden. Plant in garden beds and borders, cottage gardens, prairie and meadow plantings, rock gardens, or even xeric gardens. Blue Flax is extremely drought and cold hardy, and very easily to establish from seed. It is also somewhat tolerant or urban pollution and city sites.
