Pale flax grows as a biennial or perennial plant in dry, sunny calcareous or neutral grasslands from sea level up to 1000 m. It has long, narrow stems to 60 cm tall and slender leaves 1.5-2.5 cm long. The flowers have five petals about 1 cm long and nearly round; they are pale blue but streaked with darker colour.

Flax fibers taken from the stem of the plant are two to three times as strong as cotton fibers. Additionally, flax fibers are naturally smooth and straight. Europe and North America both depended on flax for plant-based cloth until the 19th century, when cotton overtook flax as the most common plant for making rag-based paper.
