Cherry Sparks Penstemon

The large cherry-red petals and white throats of the Cherry Sparks Penstemon make this plant a joy to behold when it is in bloom. With a longer flowering time than others, it produces tubular flowers from late spring through the summer on top of its bright green narrow leaves. Growing to less than 2 feet high and wide, this penstemon hybrid remains compact with an upright habit.

Native to North America, this Cherry Sparks Penstemon is adaptable for growing in zones 5 through to 9. It is an easy-to-care-for perennial and is most definitely a ‘thriller’ plant that is also loved by pollinators. Often grown en masse for maximum impact, this penstemon is also suited to growing ad hoc in a border or for use as a cut flower. Being heat tolerant, Cherry Sparks is ideal for planting in a south-facing border.

Cherry Sparks Penstemon Care

For the Cherry Sparks Penstemon to thrive, it requires a sunny spot where it will receive at least 6 hours of sunlight per day. A free-draining soil is a must, as penstemons struggle if grown in soil that is prone to being overly wet. With average to dry watering needs, it can tolerate a hot border, but will require more frequent watering when grown in a container. For the best results, a slow-release fertilizer can be applied in spring along with an annual ring of mulch. 

Penstemons do not require much pruning. However, as the flowers begin to die back, they can be removed to promote reblooming. 

Cherry Sparks Penstemon Spacing

The Cherry Sparks Penstemon grows to around 18 to 20 inches high with a spread of 14 to 16 inches. A spacing of 14 to 18 inches between plants is recommended when planting out a group of this spectacular beardtongue.
