Growing information:

Penstemon, also known as beardtongue, is a genus of flowering plants native to North America. 

 

Penstemon thrives in full sun or partial shade, so choose a location in your garden that receives at least six hours of direct sunlight per day. The soil should be well-draining and slightly acidic, with a pH level between 6.0 and 7.0. If your soil is heavy or clay-like, consider adding organic matter or sand to improve drainage.

Before planting penstemon, prepare the soil by removing any weeds or debris. Dig a hole that is slightly larger than the root ball of the plant. Gently place the penstemon in the hole, making sure the top of the root ball is level with the soil surface. Backfill the hole with soil, firming it gently around the plant.

Penstemon is a drought-tolerant plant, but it still requires regular watering, especially during the first growing season. Water deeply, allowing the soil to dry out slightly between waterings. Avoid overwatering, as this can lead to root rot.

Penstemon generally does not require heavy fertilization. However, you can apply a balanced, slow-release fertilizer in early spring to promote healthy growth. Follow the manufacturer's instructions for application rates.

Pruning penstemon is essential for maintaining its shape and encouraging new growth. After the flowering season, trim back the stems to about half their height. This will help prevent the plant from becoming leggy and promote bushier growth.

Penstemon is relatively resistant to pests and diseases. However, keep an eye out for common garden pests such as aphids and spider mites. If necessary, treat the affected plants with an organic insecticide or use natural predators like ladybugs to control the pest population.
