Whole plant is edible as a vegetable. Add flowers to salads, or use them as a garnish. Use leaves in salads. Seeds can be chewed, or cooked in breads and biscuits, or steamed, or roasted in the oven for 15-20 minutes at 180C and sprinkled on food like pepper. Leaves and roots can be eaten fresh. The roots are sometimes eaten like olives as an after-dinner treat, or boiled like potatoes.

As with most herbs, the health benefits can come with a price tag. Evening Primrose should be used under professional supervision, and should not be used by people suffering from epilepsy. I suggest you research further.

Gather the seeds when ripe. Grind them with mortar and pestle, store in a cool, dry place and add them to muffins, cakes, biscuits (cookies), home-made muesli, soups, stews etc.
