The word chamomile (sometimes spelled camomile, and generally pronounced with a long i) is derived from Greek—chamos (ground) and melos (apple), referring to the fact that the plant grows low to the ground, and the fresh blooms have a pleasing apple scent. Chamomile is best known for the tea that are made from dried chamomile flowers. There are two main types of chamomile that are used to produce the tea, German chamomile (Matricaris retutica) and Roman chamomile (Chamaemelum nobile). Roman chamomile is also known as Russian chamomile and English chamomile. It is a creeping perennial, ground cover that grows like a mat, and only reaches 30 cm in height. It has small daisy like flowers with yellow centers and white petals, and feathery leaves. German chamomile looks similar to Roman chamomile with the differences being that German chamomile grows upright to the height of about 30-60 cm and is a reseeding annual.
