Product Details

Rock Candy Blue Penstemon

Penstemon barbatus 'Novapenblu'

Rock Candy Blue Penstemon brings intense color to the landscape with upright spikes of vivid blue flowers that bloom from late spring through early summer. Each flower is trumpet-shaped and rises above a low mound of glossy green foliage, creating a strong vertical accent in small spaces. With a mature size of just 10 to 12 inches in height and spreading up to 12 inches in width, this variety is ideal for tight borders, front-of-bed placements, and decorative pots. Its compact size and clean form make it a great fit for commercial settings or small-scale plantings, especially in climates like North Texas where heat and sun are plentiful.

  •  A herbaceous perennial
  •  Vivid blue blooms on short flower spikes
  •  Glossy green, low-mounding foliage
  •  Upright, spreading growth habit
  •  Great for containers, borders, and mass plantings

Plant in full sun with well-drained soil. Deadhead to extend blooming and trim back in early spring. Suitable for short-term indoor display in containers with bright light exposure.
