These beautiful lavender flower buds are caffeine-free, brew a delicately purple infusion, and can be used to scent anything from desserts to bathwater. Recognized around the world for its refreshing fragrance, the lavender plant (Lavendula angustifolia) is a flowering evergreen shrub tive to the Mediterranean region. It has a long history as a healing herb Romans scented their baths with it (in fact, “lavare” means to wash in Latin) and the Tibetans still make an edible lavender butter to use as part of a traditiol treatment for nervous disorders.
