Perennial, native plant. Height 1 m to 1.50 m. Very beautiful plant, undemanding, with beautiful light, silky, glossy gray-green foliage. To be cultivated away from vegetables and aromatic plants. Very bitter, its infusion helps ward off unwanted insects (black aphid, flea beetle, piéride). When sprayed on the ground, it repels slugs. Do not spray immediately before harvest. In herbal tea, use in moderation and in very small quantities.
