Chamomile plants form soft-textured, spreading, 3 to 12 inch mats of bright, light green, finely cut, aromatic leaves. The most commonly grown form has small yellow buttons of summer-blooming flower heads; some forms have little daisy-like lower heads. Chamomile makes lawn substitute if mowed or sheared occasionally. Chamomile plants are known for their ability to be made into a tea and help with sleep and to reduce stress.
