Cuttings
Propagation of Penstemon virgatus Gray ssp. putus (A. Nels.) Crosswhite through cuttings is another method that can be used. Take cuttings from the stem tips in the spring or early summer. Dip the cut end in rooting hormone and place it in a well-draining soil mix. Cover the pot with a plastic bag to create a humid environment and place it in a shaded area. Remove the bag after a few weeks when the plant has established roots, and transplant the young plant into a larger pot or into the garden.
With proper care and attention, Penstemon virgatus Gray ssp. putus (A. Nels.) Crosswhite can be easily propagated through any of these methods.
