Photograph of a close-up of a specimen of flax, showing strands of fiber entwined to form a rope (or string?), [s.d.]. On a neutral background.; "The Linums or Flaxes form a large group of biennial, annual and perennial herbs and sub-shrubs. They form thick, upright tufts up to 2 feet high. The bluish-green foliage is linear to lanceolate and 1 to 2 inches long. The flowers are 1 to 2 inches across and come in shades of red, violet-blue, white with carmine eye, or rose pink. Each flower lasts a short time, but there are so many and they replace each other continually, over a long period. L. alpinum, the Alpine Flax, is a native of Europe. It is a pretty dwarf variety, growing 6 to 9 inches high. It has many thin, wiry stems that are covered with heath like leaves. They produce many large, pale blue flowers in June and July; it is great for growing in the rock garden. L. arboreum, the Yellow Tree Flax, is a native of Crete and forms a low, woody sub-shrub, 12 to 18 inches high; it isn't hardy in the North. There are several other kinds mentioned below in the varieties section." -- unknown author.
