Matricaria recutita, Matricaria chamomilla

Matricaria recutita can be used as a groundcover since it grows only 4 to 12 inches in height. The foliage is feathery with an apple scent, and it is accented by white, daisy-like flowers with down-turned petals.

Chamomile is most often used for medicinal purposes, and is usually administered as a tea. It is sometimes known as "the plant doctor", because it is thought to help the growth and health of many other plants, especially ones that produce essential oils.
