Answer: Verbascum are summer-blooming perennials suitable for all gardening zones. You can plant seeds or starts in a sunny site in the springtime. Helleborus grows in shade or partial shade in rich, moist, well-draining soil. Helleborus argutifolias, the Corsican Hellebore, grows best in your gardening zone and tolerates the alkaline soil so often encountered in southern California gardens.
