A reliable perennial for all conditions. An old Swiss variety, `Firebird' (also known as `Schoenholzeri') has a vigorous habit with vibrant, red trumpet shaped flowers displayed in profusion above its attractive, mounding green foliage from spring through to autumn. A great complement to the hot border.
Drought-tolerant once established, penstemons are easy care perennials for most conditions, preferring a full sun, free-draining position. Water regularly during dry periods for improved flowering and performance. Prune back to a low mound after flowering to maintain a compact habit.
