RHS Plants for Pollinators

Penstemon 'Pensham Plum Jerkum' (Pensham Series)

Good resistance to slugs and snails, but loved by bees. Flowers and foliage are resilient to rain and UK summers. Tall spikes of trumpet shaped, deep purple flowers with white throats offer a riot of colour. Best away from cold winter winds.

Plant Care

Keep well watered until firmly established. Plant into any average garden soil, avoiding wet areas. Trim off spent flower spikes and prune to shape in early spring.

Planting Instructions

Water thoroughly, or stand pot in a container of water for half an hour before planting. Dig a hole twice the size of the root ball. Remove the pot, place the plant in the hole so that the root ball is level with the surrounding ground and refill, firming if necessary. Keep well watered in dry weather. Feed in spring with a good, general fertiliser.
