Cultivation and care tips for Penstemon Spectabilis

Cultivating Penstemon Spectabilis in your own garden is a rewarding experience that requires some attention to detail. Here are some cultivation and care tips to help you grow this extraordinary plant successfully:

  • Choosing the right location: Select a spot in your garden that receives full sun to partial shade. The Showy Beardtongue thrives in well-drained soil, so make sure the planting area has good drainage. If your soil is heavy or clay-like, consider adding organic matter, such as compost, to improve its texture and drainage.
