Borago officinalis does not require starting indoors and is a fairly easygoing plant. Simply scatter the borage seeds into the ground or into a planter. Mid-April to early May is the best time to sow, until the first of July, but not after that. You can transplant young plants that are purchased around the middle of May.

Grow the plant in a sunny spot with well-drained fertile soil. It requires a dedicated space in the garden. It is highly recommended for butterfly or vegetable gardens as it helps attract pollinators. Planting with strawberries attracts bees. Companion plant suggestions include strawberries, tomatoes, and zucchini or squash.

Trichomes, which are tiny hairs, are present on the leaves and stems. The lance-shaped, dark green leaves can reach a length of 10 to 15 centimeters. Depending on the cultivar, borage plants bloom in either white or blue between May and July.

The drupe-like fruits that are produced after the star-shaped flowers are pollinated are a characteristic of the Boraginaceae family. The seeds are housed within the four nutlets that make up each drupe.

Propagating Borago officinalis

Borago officinalis dies down in the winter, but you will not need to buy seeds as it self-seeds quite vigorously and spreads around the garden. Luckily, it is so attractive that it adds to the general design.

If Borage pops up in unwanted garden spaces, weed out your planting beds is very easy.

Borage Seeds

Start seeds indoors in peat pots or sow directly in garden beds in early spring. Seeds are best sown in the full or partial sun under 1cm of soil and then covered with a bit of soil or compost. This annual will remain in the garden from year to year by self-seeding.

Consider planting borage in your vegetable garden with strawberries, tomatoes, and zucchini/squash.

If the plant appears in unwanted garden spaces, simply weed it out of your planting beds, which is very easy.

Pruning Bourrache officinale

Cut back just before it flowers if you want to enrich the soil and suppress weeds. However, they won’t set seed if you cut them back early. If your primary goal is to attract pollinators, cut back after the flowers have finished blooming. This will result in self-seeding.
