Chamomile is a cheery herb that can add beauty to a garden and may have sedative qualities. Chamomile growing in the garden is both useful and visually pleasing. Chamomile grows best in cool conditions and should be planted in part shade, but will also grow full sun. The soil should be dry. Once your chamomile is established, it needs very little care. Like most herbs, chamomile grows best when it is not fussed over. Too much fertilizer will result in lots of weakly flavored foliage and few flowers. Chamomile is drought tolerant and only needs to be watered in times of prolonged drought.
