Also called false indigo for the rich blue shade of its flowers, this hardy perennial fills the spring garden with elegant spires of pealike blooms. It withstands drought -- and deer, rabbits, and other critters leave it alone. The bluish-green foliage looks great all summer long, and the charcoal-black seedpods create fun contrast in fall. Name: Baptisia australis Zones: 3-8
Genus: Campanula persicifolia Zones: 3-7 Bloom time: June; then six weeks later. To prune: Snip spent flowers promptly, without removing developing buds. Good to know: In hot regions, this one fares best in partial shade.
