Summary

Penstemon barbatus, commonly known as Golden Beard Penstemon or Beardlip Penstemon, is a perennial herb that is native to the rocky slopes and open woodlands of the southern Intermountain West, including regions from Arizona and New Mexico north to Utah and Colorado, as well as extending into northern Mexico. It typically grows to a height of 1 to 3 feet (0.3 to 0.9 meters) and a width of 1 to 2 feet (0.3 to 0.6 meters). This species is characterized by its erect growth habit and spikes of clustered, tubular, scarlet blossoms with yellow hairs on their lower lip, which bloom from late spring to early summer. The flowers are highly attractive to hummingbirds and are quite showy, making them a highlight in any garden setting.

Golden Beard Penstemon is valued for its striking flower spikes, which add a splash of color to the landscape. It is a popular choice for xeriscaping due to its low water requirements and is also used in conventional gardens. The plant has been bred to produce several cultivars with varying flower colors, enhancing its ornamental appeal. It thrives in full sun and requires well-drained soil, making it suitable for rock gardens and border fronts. While generally low-maintenance, it can be susceptible to root rot if overwatered or planted in poorly drained soils. It is also important to note that while Penstemon barbatus is not typically invasive, it can self-seed in ideal conditions.CC BY-SA 4.0
