Penstemon confertus, commonly known as Yellow Penstemon, is a perennial herb native to the open, rocky habitats of British Columbia, the northwestern United States, specifically in areas such as the eastern slopes of the Cascades, the Blue Mountains, and the northern Rocky Mountains. It typically grows to a height of 1-3 feet (0.3-0.9 meters) with a similar spread. The plant forms upright clumps and is characterized by lance-shaped leaves and dense clusters of tubular yellow flowers that bloom from late spring to early summer, providing a showy display that attracts pollinators such as bees and hummingbirds.

Yellow Penstemon is valued for its bright, cheerful flowers and its adaptability to dry, rocky sites, making it an excellent choice for rock gardens, native plant landscapes, and xeriscaping. It is drought-tolerant once established and requires minimal maintenance. In cultivation, it thrives in full sun and well-drained soils, and it is best to avoid overwatering to prevent root rot. While generally disease-resistant, it can be susceptible to root rot in poorly drained soils and may be affected by foliar diseases in humid conditions. This species is not known for aggressive roots or significant invasiveness issues.CC BY-SA 4.0
