Firestem is the common name for Penstemon rubicundus which is a medium sized shrub with masses of brick red flowers with a pure white throat late summer and early autumn. The shrub grows to approximately 90 cm in height and 50cm in width. Penstemon rubicundus prefers a sunny aspect with moist but well drained soil. It is a vigorous grower and will tolerate light to moderate frosts and some shade. A medium prune and feed with Osmocote Outdoors Trees & Shrubs after flowering will keep the plant compact and healthy.
Penstemons are a great addition to any garden. They can be used as a specimen plant, tub plant, en masse for an eye catching effect or even as a low hedge. Firestem looks good planted with other Penstemons like Gladiator, Swanlake Osprey and Flamingo. Done this way and you will have a sea of color swaying in the late summer breeze. Firestem also looks great intermingled with Gaura’Corrie’s Gold’, Lavandula ‘Hazel’ or Campanula ‘Cherry Bells’
