Flax Overview

A genus of around 140 accepted species of annuals, biennials or perennials, herbaceous or evergreen, and some shrubs in the Linaceae family found in most temperate and subtropical zones worldwide. Included in the genus is common flax, L. usitatissimum, cultivated for flax fibre used to make linen and for its seeds used in linseed oil production. Some species are popular garden ornamentals grown for their attractive bowl-shaped flowers in shades of blue, red and yellow.
