What does Common flax look like?
Common flax is an upright annual plant reaching up to 1.2 meters tall, with slender stems and narrow, blue-green leaves. Its flowers are about 1.5 to 2.5 cm wide, each with five petals that may be blue, white, yellow, or red. After flowering, it forms round, dry capsules containing glossy brown seeds. The plant is grown both for its attractive flowers and for its useful seeds and fibers.
Where does Common flax come from?
Flax was first domesticated in the Fertile Crescent, with wild relatives found from the eastern Mediterranean to India. Archaeological finds in Georgia show humans used wild flax fibers 30,000 years ago. Domesticated flax spread to Egypt, where linen became important for clothing and burial, and later to Europe and Asia. The species is known only as a cultivated plant, with no wild populations of Linum usitatissimum itself.
When and how Common flax blooms
Flax is sown in temperate climates, preferring deep, organic-rich loam soils. It grows quickly, reaching maturity in about 100 days. The plant is harvested for fiber when the stems begin to yellow, and for seed when the capsules are ripe. Fiber is extracted by pulling up the whole plant and retting the stems to separate the fibers, while seeds are collected and pressed for oil.
How Common flax is used
People grow flax mainly for its fibers, which are spun into linen for textiles such as sheets and clothing. The seeds, called linseed or flaxseed, are eaten whole, ground, or pressed for oil used in foods and wood finishing. Flax is also grown as an ornamental garden plant. The by-products of oil extraction are used for animal feed.
Kinds of Common flax
There are two botanical varieties: Linum usitatissimum var. usitatissimum and var. stenophyllum. Other species in the genus Linum may have similar flowers in different colors and may be perennial, but common flax is always an annual. Yellow-seeded types, called solin, are grown for oil with a similar profile to brown seeds.
What Common flax means
Flax has played a major role in human history, especially for linen production in ancient Egypt and Europe. Egyptian priests wore linen as a symbol of purity, and linen was used to wrap mummies. The plant's name means 'most useful', reflecting its many uses. Flax was once the main source of plant fiber for cloth in Europe and North America before cotton became dominant.
