Tall bellflower (Campanulastrum americanum [formerly Campanula americana]) usually isn’t much to look at during its first season, when it forms clumps of elliptical, medium green leaves. The species is variable and behaves differently in different growing conditions: It might flower in mid to late summer the first year or wait until the second year to send up stems that can reach anywhere from 2 to 6 feet tall, with light to medium purple-blue, flat, star-shaped flowers in early to midsummer. Each bloom drops off quickly, but new ones open daily as the stem rises. Native to much of the eastern half of North America, tall bellflower is charming in a cottage-garden setting or a woodland planting. Full sun (in cooler areas, if the soil is on the moist side) to partial shade (morning sun and afternoon shade is ideal). Usually biennial but possibly annual; best in Zones 4 to 7.
