How to care for Penstemon Pensham Plum Jerkum (Pensham Series):
Plant penstemons in well-drained soil in a sunny or lightly shaded position, incorporating compost or well-rotted manure to improve fertility. Water regularly until established, then reduce watering, as they prefer drier conditions once settled.
Deadhead faded blooms frequently to extend the flowering season. In autumn, leave the top growth in place to provide winter protection, then cut back in spring when new shoots emerge lower down the stems.
Apply a dry mulch, such as bark or composted straw, around the base in colder regions to insulate the roots from frost. Every few years, lift and divide congested clumps in spring to maintain vigour and encourage fresh growth.

Please note:
This perennial dies back to below ground level each year in autumn, then fresh new growth appears again in spring.
