What is sorrel, what is it good for and how do you grow it at home?
Sorrel (Rumex acetosa), also known as garden sorrel, is a perennial leafy plant with a distinctive tangy, sour flavour thanks to its high oxalic acid content. It has been used for centuries in cooking and natural medicine – as a refreshing addition to dishes, but also as a plant that stimulates digestion and strengthens the immune system.
Beyond its distinctive flavour, sorrel is rich in vitamins A and C, iron, potassium, magnesium and fibre. It is especially valued for its antioxidant effect and positive impact on the digestive system.

Growing sorrel at home
Sorrel thrives in gardens, on balconies or in containers indoors. It prefers moist, humus-rich soil and semi-shaded positions, although it tolerates sun if there is enough moisture. Thanks to its hardiness it can be grown for most of the year.
In smart gardens such as SIMPLY and AURELIA, sorrel is grown simply and without transplanting – automatic watering and LED lighting ensure a constant supply of fresh leaves.
