Penstemon 'Swan Lake'
A neatly mounding penstemon with evergreen foliage and compact white summer flowers held vertically on tall spires to 60cm, Penstemons are like mini perennial Foxgloves, only tougher.
Drought-tolerant once established, penstemons are easy care perennials suitable for most conditions. Plant in full sun in an enriched, free-draining soil. Water regularly during establishment and extended dry periods for improved flowering and performance. Prune back to a low mound after flowering to maintain a compact habit.
