Description

Penstemon heterophyllus is a perennial herb producing upright, branching stems easily exceeding one meter in height and becoming woody at the bases. The leaves are variable in shape and may reach nearly 10 centimeters long. The inflorescence produces several wide-mouthed tubular flowers up to 4 centimeters in length. The flowers may be shades of blue or purple to nearly magenta.[1]

Cultivation

Penstemon heterophyllus is cultivated as an ornamental plant by plant nurseries. It is used as a flowering perennial for traditional flower beds, and in native plant, drought-tolerant, and habitat gardens and public landscapes.[2][3][4] It is a nectar source for (native) birds and butterflies.[4]

Several cultivars have been selected for flower color and plant form, for use in Mediterranean climate and other low-water-use gardens, including:

• Penstemon heterophyllus 'Electric Blue' — intense blue flowers.[4]
• Penstemon heterophyllus 'Margarita BOP' — sky blue to reddish purple flowers.[5]
• Penstemon heterophyllus 'Blue Springs' — bright blue flowers.[6]
