  • - Avoid heavy fertilization, as Penstemon performs best in leaner soils

Pruning and Training:

  • - Cut back stems after flowering to promote new growth and prevent leggy growth

Additional Pest Management:

  • - Penstemon is generally pest-free but may occasionally attract aphids or slugs; monitor as needed
  • - Ensure good air circulation to prevent powdery mildew and other fungal issues

Blooming Indicators:

  • - Blooms from late spring to early summer with tubular flowers in shades of pink, purple, red, or white

Dark Towers Penstemon

Newly planted but excited about how they will look when mature. They already bloomed this season.
