Artemisia

With beautiful silver foliage or narrow fern-like leaves, these plants are perfectly suited to a hot dry garden, or one by the seaside. Foliage is often very scented and has various culinary uses. A. dracunculus is the herb tarragon, or French tarragon, A. absinthium, wormwood, is used to flavour 'verte absinthe', a strong spirit. For much of the 20th century it was banned in Europe and the US due to its possible harmful effects!
