About Scarlet Flax: This beauty originally comes from northern Africa and southern Europe, specifically native to the country of Algeria. Members of this plant family were once used to weave linen because of the valuable fibers in their stems. According to historical record, Romans also used these fibers to weave ropes and sails for their ocean-going vessels. The genus name Linum means “flax,” while the species name “grandiflorum” means “large-flowered.”
Scarlet Flax Germination: Direct sow in fall for the earliest blooms, or after the last spring frost for early summer bloom. Plant just below the surface of the soil. A new crop can be planted every several weeks for continuous blooming until frost. For best results do not start these plants indoors, since they do not transplant well.
Growing Scarlet Flax Seeds: These plants tolerate drought well and flourish in light, sandy soil. They attract bees and butterflies and readily reseed themselves.
Harvesting Scarlet Flax: These blooms make excellent cut flowers. Choose stalks with flowers that have just opened and place them in water immediately; strip the foliage that will fall below the surface of the water.
Saving Scarlet Flax Seeds: Allow the seed pods to dry completely on the stem; break them open to collect the flat, brown seeds. Store them in a cool, dry place.
