Penstemon 'Blackbird'
Ever-reliable and hardy, penstemons are long flowering, easy-care perennials that are invaluable in the garden. With rich burgundy tubular flowers that hang elegantly from its stems, ‘Blackbird’ makes a striking combination with grey foliaged plants in a border garden.
How to grow
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.
