German Chamomile (Matricaria recutita) is a low-growing annual that forms a feathery, fern-like mat of bright green foliage rarely exceeding 6–9 inches tall. From this carpet rise slender, branching stems up to 2–3 feet high topped with small, classic daisy-like flowers—white petals surrounding a golden-yellow center—each under 1 inch across.
 
Hardy in zones 5–8 (often grown as an annual), it prefers full sun to light shade and light, sandy, well-drained soil. Space plants 8 inches apart and water occasionally; established plants are fairly drought-tolerant.
 
It spreads both by creeping stems that root where they touch soil and by abundant self-seeding, so under ideal conditions it can become quite vigorous.
 
A valuable companion in vegetable gardens, German chamomile repels cucumber beetles and is rarely bothered by pests (aphids can be hosed off if they appear). For thousands of years it has been prized as a gentle herbal remedy, especially for calming anxiety, promoting sleep, and soothing upset stomach, gas, and diarrhea.
 
Sold in a 2.5" pot.
