Growing medicinal plants in the garden has a long tradition in human history. The Celts are known to have cultivated nettles and valerian and knew about their health benefits. But even in modern gardens, medicinal plants are still an integral part of garden design, knowing about their many uses. Freshly picked chamomile blossoms prepared as tea, a red oil made from St. John’s wort or a self-made tincture of echinacea enrich the natural medicine cabinet. Many blooming medicinal plants are also a welcome source of food for insects and they look very attractive. Medicinal plants, which are usually quite undemanding, can thrive together in their own 'apothecary’s bed' or can be planted together with food plants or flowers.
