A hardy annual native to the western United Satates and adapted to very arid environments. The stunning deep blue, bell-shaped flowers are highlighted by long golden stamens. Leaves are heart-shaped, covered with soft white hairs closely resembling an African Violet. Prefers full sun in very sandy or well-drained soils. Sow in early spring, seedlings are not winter hardy. One of Mother Natures most extravagant shades of blue. The plant does well in poor sandy soil and makes a splendid pot plant.
