There are two kinds of chamomile. The first is Roman chamomile (Chamaemelum nobile) and the other is German chamomile (Matricaria recutita). The Roman variety is the true chamomile but German chamomile is used herbally for nearly the same things. The steps for growing Roman chamomile and growing German chamomile are also nearly identical. Roman chamomile is also known as Russian chamomile and English chamomile. It is a creeping ground cover that grows like a mat. It has small daisy like flowers with yellow centers and white petals. The leaves are feathery. It is a perennial. German chamomile looks similar to Roman chamomile with the differences being that German chamomile grows upright to the height of about 1 to 2 feet (30 to 61 cm.) and is a reseeding annual.
Chamomile is drought tolerant and only needs to be watered in times of prolonged drought.
