Rue (Ruta graveolens) subshrub up to tall. This herb plant has a nice mounding habit and small, pungent evergreen leaves. Tiny yellow flowers grow above the attractive foliage. Rue will work nicely in an herb garden as well as a rock garden.
Chartreuse green buds open wide into handsome, creamy-white flowers flushed with the palest of green tints. The flowers are lovely grown on trellises and arbors, blooming from midsummer until hard freeze.
