It’s low-growing, so it makes a charming ground cover or pot filler around taller flowers. Roman chamomile can grow in zones 3-9.

Does chamomile spread easily?

Chamomile plants may range in height from 6-18 inches (15-46 cm.) with an equal spread, depending upon type. All chamomile types produce an abundance of seed that will quickly self-sow wherever it lands in warm, loose soil.

Do chamomile come back every year?

Roman chamomile is a perennial, growing from the same root year after year. German chamomile is an annual, but don’t expect it to grow in the garden for just one year! It self-sows freely and you can bet if you plant it one time, it will spring up in the garden from then on.
