Several types of flax can be grown in the perennial garden. Most need winter protection and grow best when given full sun and any garden soil. Some tolerate soils with a pH above 7.
Propagation is by seed, division or cuttings. The seed germinates in 3 to 4 weeks at temperatures between 65 and 75 degrees. The plants may be divided in spring or fall. Cuttings of half ripened wood are taken in August and inserted in a coldframe to root.
Linum alpinum--Alpine flax Alpine flax has a tufted habit, grows 6 to 9 inches tall and produces blue flowers in June and July or possibly into August.
Linum flavum--Golden Flax. The flowers are yellow and produced June through August. The plant grows one and one-half to two feet tall.
Linum narbonense--Narbonne Flax This flax grows 18 to 24 inches tall and bears blue flowers June through August. It prefers a sunny location and a moist, sandy, well drained loam. Set the plant 12 inches apart and propagate by division or stem cuttings. Give the plants some winter protection.
Linum perenne--Perennial Flax Perennial flax produces blue flowers during June and July and grows 12 to 18 inches tall.
