Perennial flax morphology

A densely clumpy durable plant, which distinguishes it from the fibrous and oily varieties of flax, which are annuals.

The aboveground shoots are strongly branched, spiral foliage, bare and upright. They only branch at the top.

The leaves are asymmetrical and thin, lancet-like shaped.

The flowers are typical for flax: five-petalled, fast-drooping, on raised peduncles, with blunt tepals, pale blue in color (wild type, most varieties, especially ‘Saphir’ and ‘Nanum Saphir’), less often white (varieties’ Alba ‘,’ Nanum alba ‘and’ Diamond ‘). The clustered in corymbose inflorescences are blue. It blooms in June and July.

The fruit in the form of a brown capsule on a stiff, erect stalk. The single seeds covered with a thin film, measure up to 4.5 mm in length.

Additional information


Perennial flax likes sunny places, and ground heavily drained or permeable, sandy. It perfectly tolerates drought as well as the deficiency of nitrogen, and phosphorus in soil. It is not very picky about the pH of the soil, grows well on acidic and peaty soils together with  heathers, and on alkaline, highly lime grounds. Recommended sowing spacing 6-16 specimens per m2, 25-41 cm. It sprouts better in spring than in autumn. It doesn’t like transplanting. It looks great in balcony containers, flower walls, naturalistic beds, rockeries and heather gardens, as well as cover of taller perennials, in the company of fescues, carnations, heathers and rock roses. Perfect for dried flower bouquets. Might need cover for winter against humidity and frost.

Interesting facts

The determination of the original homeland, and thus the native nature of this flax in particular regions of Poland, raises considerable disputes among botanists. Some treat high-mountain forms of flax as a subspecies or ecotype of perennial flax, others as a separate species, called Carpathian flax Linum extraaxillare.. Lowland and upland forms are native to south-eastern Europe, in Poland cultivated only, then temporarily going feral.
