Answer: Chamaemelum nobile, or Chamomile, forms a soft-textured, spreading mat 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 daisylike flower heads. It makes a great groundcover or lawn substitute, especially if mowed or sheared occasionally.
Chamomile will continue to spread and will eventually fill in the gaps, but you can encourage this outward growth by clipping the foliage back a bit. You can reseed next spring, or dig and divide the plants, or just be patient and allow the plants to fill in at their own pace. Regular clipping or mowing will keep the plants neat and produce additional lateral growth.
