Germination Information: There’s varying advice out there about the best way to get the seeds going. One option is to surface-sow them outdoors in fall through midwinter in a pot or milk jug (using the winter-sowing method) for germination in spring. Some sources say that increases the odds the plants will flower the first year; my winter-sowed seeds, however, waited until the second year to bloom.

Other advice suggests starting the seeds indoors under lights in warm conditions in late winter to early spring, or outdoors in late spring to early summer. The seeds supposedly need a cold period of at least a month to sprout. However, I have had luck starting them without the chilling period: surface-sown seeds planted on March 6 started germinating on March 12. Your experience may vary.

If you allow seeds to form after flowering, the plants are likely to self-sow.

Description

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.

Collected in early September 2023. At least 25 seeds. Unknown ecotype. Shipping to US addresses only.
