Chrysanthemum (Chrysanthemum coronarium) The whole plant has a very distinctive aromatic flavour and is rich in vitamins and minerals and potassium. Older leaves and the centre of the flower may be a little bitter. The open flowers and unopened flower buds (pearls) can be used to make a tea. Chrysanthemum tea is a beautiful yellow colour with a very pleasant aromatic flavour. Flowers can be used fresh or dried. As a point of interest all Chrysanthemum flower petals are edible raw.
