Characteristics of Linum usitatissimum (Flax, Linseed) Expand

Center of Origin Reproduction Toxins Allergenicity

The species is believed to have originated in the region east of the Mediterranean, towards India.

Flax is self-pollinated. The pollen is too heavy and sticky to be transported by wind, and the flowers do not attract insect pollinators.

The immature pods of the flax plant are poisonous. 

Allergic reactions have been associated with contact with flax seed and seed powder.
