Penstemon Cambridge Mix

The perennial that starts in June and is often still flowering at Christmas. Penstemon Cambridge Mix produces tubular, foxglove-like flowers in jewel tones of rich crimson, deep purple, bright pink, and cool blue — often with contrasting white throats — on bushy, semi-evergreen clumps that provide structure and colour for months when lupins and delphiniums have long finished.

A top-tier bumblebee plant. Do not cut back in autumn — leave old stems as frost protection and cut to new growth in April. Approximately 100 seeds per packet.
