Ajwain plant (Trachyspermum ammi), or carom, is an aromatic herb grown for its pungent, thyme-like seeds and fragrant leaves. It forms a soft, feathery bushy plant with finely divided foliage and clusters of tiny white flowers that ripen into the familiar ajwain seeds. The leaves and seeds carry a sharp, spicy aroma and are valued in Indian cooking and home remedies for digestion. Easy to grow in pots and kitchen gardens, ajwain prefers full sun, warm conditions and well-drained soil. It is a useful, low-maintenance culinary and medicinal herb for any Indian home garden.
