Flax (Linum usitatissimum), seeds with medicinal properties

Linen (Linum usitatissimum) is a very hardy, decorative, elegant and very easy to grow plant. It is a herbaceous plant with fibrous stems branching in the form of a corymb, which is mainly found in temperate and subtropical regions of the northern hemisphere. The thin stems bear leaves 1 to 3 cm long, narrow and lanceolate, of a glaucous bluish green color. Its flowers are so light that they move with the slightest breeze all summer long. They have 5 light blue petals, are funnel-shaped and measure 2 to 3 cm in diameter. They form terminal panicles, and are carried by an erect and elongated peduncle. But they fade during the day!

The fibers of flax are used in the making of fabrics (batiste), ropes, or construction materials for their insulating power. Linseed oil, rich in polyunsaturated fatty acids, in particular omega 3 and omega 6, is extracted from its seeds: it is used in cosmetics, pharmaceuticals and food. But for a very long time, flax seeds have also been used as a laxative, as well as to calm hot flashes associated with menopause.

Flax versus Colorado beetle

Anyone who has ever grown potatoes knows that Colorado beetles creep in slowly but surely and wreak havoc on your crop in a matter of weeks if you do nothing.

Colorado beetle larvae (7/8 mm) become winged adults (1.5 cm), striped with yellow and black.

To overcome this invasion of Colorado potato beetles in your potato plants, no need to spray powders and products that are more harmful than each other!

Just sow a few flax seeds between your potato rows and you'll be surprised how the Colorado beetles will spare your vegetable patch. The few Colorado beetles who will come to "visit" you will be easy to master.

I invite you to leave a comment to share your opinion, your experience or ask your questions on the subject.

You will find some good addresses in the column opposite: organic vegetable seeds, gardening equipment, greenhouses. I only recommend companies and associations that I appreciate, that I have tested and that have given me complete satisfaction.
