Ruda is an aromatic herb, also called rue. The scientific name is ruta graveolens. Rue is a native of the Mediterranean region and is a good ornamental plant for herb gardening. This herb plant has a nice mounding habit and small, very pungent evergreen leaves, and tiny yellow flowers grow above the attractive foliage. Rue also works nicely in rock gardens.
