Boysenberry Taffy produces large bell like deep berry wine blooms with a smaller white throat, over many months of repeat flowering flushes. Multiple flower spikes appear on a fuller bush than older penstemons. Flowers have numerous large trumpets with a striking white throat. Plant in clumps for a romantic cottage effect!
Dead heading of spent flower spikes will cause additional laterals to form. Prefer average well drained soil, do not mulch over crowns. Drought and humidity tolerant
