Campanulastrum americanum (American Bellflower)

Indigenous to North America, Campanulastrum americanum, also known as American Bellflower, stands tall as an upright annual or biennial, showcasing elevated flower stems adorned with coarsely textured, serrated, lance-shaped green leaves. As summer unfurls, the upper reaches of these stems are adorned with striking, flat, star-shaped lavender-blue flowers, each measuring 1 inch in diameter (2.5 cm). These delicate blossoms wield a magnetic attraction for hummingbirds. With the passage of time, the petal tube of each bloom elongates, revealing a white ring at the throat. These flowers grace the plant singularly or in clusters, emerging from the junctions of the upper leaves. Their charm is both captivating and enduring, with the added benefit of extended persistence if regularly deadheaded. Depending on the timing of germination, this plant showcases itself as either an annual or a biennial. It dedicates its first year to producing foliage, reserving its second year for the grand display of blooms.
