How to care for Penstemon Pensham Plum Jerkum (Pensham Series):
Remove the faded blooms regularly to prolong flowering. Apply a dry mulch around the base of the plant to protect the roots from frost damage in autumn. Leave the old foliage to protect the new shoots from frost and then cut it back by a third in spring.
Please note:
This perennial dies back to below ground level each year in autumn, then fresh new growth appears again in spring.
