Penstemon campanulatus, commonly known as Bellflower Beardtongue, is a perennial herb native to the open woodlands and grassy slopes of Mexico. It typically grows up to 1 meter tall and has a clumping form with erect stems. The large, bell-shaped purple flowers bloom in early to mid-summer and are quite showy, attracting both gardeners and pollinators alike. The foliage is lance-shaped and sometimes has a bluish-green hue.

Bellflower Beardtongue is valued for its striking floral display and its ability to attract hummingbirds and bees, making it a popular choice for wildflower gardens, natural landscaping, and pollinator-friendly plantings. It is also used in border plantings and as a cut flower due to its tall, upright growth habit. This species thrives in full sun and requires well-drained soils; it is relatively drought-tolerant once established, making it suitable for xeriscaping. While generally low-maintenance, it can be susceptible to root rot in poorly drained soils and may suffer from powdery mildew. To promote vigorous growth and flowering, deadheading spent blooms is recommended.CC BY-SA 4.0
