The Witching Herbs, is an in-depth exploration of 13 essential plants and herbs most closely associated with witchcraft--13 because it's the witching number and reflects the 13 months of the lunar calendar. The plants are poppy, clary sage, yarrow, rue, hyssop, vervain, mugwort, wormwood, datura, wild tobacco, henbane, belladonna, and mandrake. The essential plant-worker's guide. Roth is not only a successful gardener, but also a magician and scholar of the occult. No other book blends clear, practical gardening techniques with equally lucid and sophisticated plant magic so successfully. Paperback.
