Both the leaves and the flowers of chamomile have a wonderful fruity flavor and aroma. It is usually the chamomile blossoms, rather than the leaves, that are harvested for tea.
The best stage to harvest the flowers is when the ray florets, the white petals on the outside of the flower, are pointing straight outwards, horizontal to the flower.
Another method, drying in the food dehydrator, is a quick and easy method. A lined dehydrator tray can help to prevent too much movement of the small white flowers while they are drying.
