Perennial Flax
Linum perenne

Linaceae

Thin, arching stems bear fine, narrow blue-green leaves. Foliage is inconsequential; cornflower blue flowers about an inch wide burst forth in airy panicles, making this a lovely plant for less-formal gardens. Flowers bloom for four to six weeks, then again in late summer.

Additional Comments: Requires well-drained soil. The more compact L. perenne ssp. alpinum (Alpine flax) grows 8 to 12 inches tall but does not bear as many flowers. L. perenne 'Saphyr' grew about as tall as the species (28 inches) but flowers are a richer blue. All three (species, ssp. alpinum, and 'Saphyr' bloomed a second time in September. None grew as well in 2003 as it did in '02. Once used in linen and rope production, L. perenne is more popular now as a garden plant. The annual L. usitatissimum now is utilized mostly for fiber and oil. Short-lived, but reseeds liberally.
