"The Nierembergia Blue Eyes, 'Nierembergia', a Proven Selections plant, is a veritable bushel of blooms. The bicolor Blue Eyes is perfect for baskets. They flower all summer long and they are unfazed by heat and humidity. The one inch white saucer shaped blossoms have lavender and blue centers and are delightful on wispy upright stems.For zones 8-11, this plant can also be a perennial."
