Plant closer together for baby leaves or roughly every 6 inches for larger leaves. Great unique taste. Garden sorrel is the standard sorrel variety and an indispensable green in European and Mediterranean cooking. Its long broad kelly green leaves are tangy and succulent, much like the texture of spinach, with lemon undertones and an acidic finish which may be due to its high oxalic acid content. Sorrel is a good complimentary herb to pair with fish or rich fatty meats. It also makes a great puree, sauce or soup.
