About Lewis Flax: As the name indicates, this native flax was discovered by Meriwether Lewis of the Lewis and Clark expedition. Lewis collected the first specimen on July 9, 1806 near the Sun River in Montana. Botanist Frederick Pursh, who studied the plants gathered on this expedition, first published a description of this plant in his 1814 publication of Flora of North America. Native Americans once used the fibers of this plant for weaving fabric, string, nets, and baskets.
Lewis Flax Germination: Direct sow in late fall or early spring, planting just below the surface of the soil. This species does not transplant well.
Growing Lewis Flax Seeds: Water occasionally, controlling weeds to allow the seedlings to become established. Full growth and flowering usually does not occur until the second season of growth. Mature plants tolerate drought well, but flourish with occasional watering. Unless the seeds are being harvested, cut back the plant after flowering to allow for new growth next season.
Harvesting Lewis Flax: These blossoms do not perform well as cut flowers, and are best enjoyed outdoors.
Saving Lewis Flax Seeds: Allow the seed pods to dry completely on the stem; break them open to collect the flat, dark seeds. Store them in a cool, dry place.
