A knot garden is a garden style that was popularized in 16th century England and is now considered an element of the formal English garden. A knot garden consists of a variety of aromatic and culinary herbs, or low hedges such as box, planted in lines to create an intertwining pattern that is set within a square frame and laid on a level substrate. The spaces between these lines are often filled with stone, gravel, sand or flowering plants. Traditional plants used in knot gardens include germander, marjoram, thyme, southernwood, lemon balm, hyssop, costmary, acanthus, mallow, chamomile, rosemary, calendula, viola and santolina.
