French Sorrel, Rumex acetosa.
It's an incredibly easy plant to grow—other than occasional weeding and harvesting, sorrel doesn’t need much babysitting in the soil. It’s a perennial, fast-growing, and winter-resistant green, meaning if you're looking at a spring garden, you should stock up on sorrel.
Produces some of the earliest greens of spring and the latest of fall. The tender, fresh green leaves grow to about 8" long and have an intense lemony flavour. Use sparingly in salads or generously in soups and sauces, especially with fish.
Sorrel is loaded with vitamins A and C, which are great for your immune system. Besides boosting up your fish entree, the leafy green also gives a good boost for your heart health. Its high potassium content can play a welcome role in lowering your blood pressure, and it increases blood circulation.
