The leaves are narrow and usually range from 1 to 2 inches in length, with margins that may or may not be hairy. The plant produces beautiful tubular blue or lavender flowers that are about an inch in length.
Common Names
Peck's beardtongue is also commonly known as Peck's penstemon, Peck's beardlip, and Chaparral penstemon.
Uses
Peck's beardtongue has several uses. It is commonly used as an ornamental plant in gardens and landscaping. It attracts bees, butterflies, and hummingbirds, making it an excellent choice for pollinator gardens. The plant's roots are also used by indigenous people in the southwestern United States for edible and medicinal purposes. The roots are used to make teas, tonics, and poultices to treat various ailments, including respiratory and digestive issues.
Light Requirements
Penstemon peckii Pennell plants typically grow best in areas that receive plenty of sunlight. They require direct sunlight exposure for at least six hours per day to produce the best blooms.
Temperature Requirements
These plants prefer moderate temperatures. During the growing season, which runs from spring through autumn, the average temperature should not exceed 75°F (24°C) during the day or fall below 55°F (13°C) during the night. During the dormant season, which occurs in winter, they can withstand colder temperatures but may die if the temperature falls below 20°F (-6°C).
Soil Requirements
The plant Penstemon peckii Pennell thrives in well-drained soil with a slightly acidic pH level of 5.5-6.5. They can also grow in sandy or rocky soil types, as long as the drainage is adequate. Adding compost or organic matter to the soil can help improve its fertility and water retention ability.
Cultivation
Penstemon peckii Pennell, commonly known as Peck's penstemon, is a native plant of the USA, found in drylands, grasslands, and open forests. It can thrive in several soils, such as rocky, sandy loam, or clay soils. It is essential to plant them in well-draining soils that retain moisture appropriately.
The plant requires full sunlight to part shade to grow to its fullest potential. Partial shade can also be favorable in hot, dry regions to prevent heat stress to the plant.
Watering Needs
Peck's penstemon is a drought-tolerant plant, and after its establishment, it requires moderate watering. The plant prefers evenly moist soil, and water needs vary throughout the year. During the growing season, the frequency of watering should increase to keep the soil moist. On the other hand, during the dormant season, limit the watering as the plant can tolerate dry soils.
Fertilization
Peck's penstemon grows naturally and does not require fertilizer. Gardeners can add a slow-releasing fertilizer with equal nitrogen, phosphorus, and potassium levels. Furthermore, over-fertilizing the plant can lead to excessive vegetative growth and reduced blooming.
Pruning
Peck's penstemon does not require regular pruning as it prefers to grow naturally. However, deadheading should occur to encourage continued blooming. Cut back the plant's stems after flowering while retaining enough stem to maintain the plant's shape. Additionally, the plant's foliage should be removed periodically to improve air circulation, which helps prevent diseases and pest infestations.
Propagation of Penstemon Peckii Pennell
Penstemon peckii Pennell is a herbaceous perennial plant, native to North America. It is commonly known as 'Peck's penstemon'.
Propagation methods
Peck's penstemon can be propagated by seed or vegetatively using stem cuttings or division.
Propagation by seed
The seeds of Penstemon peckii Pennell can be sown directly in the garden or started indoors. Sow the seeds in early spring in a seed tray, placing them on top of a well-draining soil mix without covering them. The tray should be kept moist and in a place with bright light until the seedlings emerge. After emergence, the seedlings can be transplanted to individual pots and grown for a few more weeks before transplanting into the garden.
Propagation by stem cuttings
Take stem cuttings from new growth in the spring or early summer. Cut the stems about 4 to 6 inches long and remove the lower leaves from the stem. Dip the cut end in rooting hormone, and plant the stem into a pot with well-draining soil mix. Water the cutting and keep the soil moist, placing the pot in a warm, bright spot out of direct sunlight. After some weeks, roots will start to grow, and the plant can be transplanted to the garden.
Propagation by division
Peck's penstemon can also be propagated by division in the spring or fall. Dig up the plant and use a sharp knife or garden fork to divide it into smaller sections with healthy roots and shoots. Plant each section in a new, well-draining soil mix and keep the soil moist until the new plant establishes itself.
Propagation of Penstemon peckii Pennell is relatively easy, and it is a great way to increase the number of these attractive plants in the garden.
Disease and Pest Management for Penstemon peckii Pennell

- Root rot: Root rot is mainly caused by overwatering or poor drainage. It can cause yellowing of leaves, wilting, and deterioration of roots. To manage root rot, cut off the affected parts and improve the soil drainage.
- Powdery mildew: Powdery mildew appears as gray or white powdery spots on the plant. It thrives in humid conditions and can spread to other plants. To manage powdery mildew, avoid overhead watering and remove the affected parts.
- Rust: Rust is a fungal disease characterized by orange spots on the leaves' undersides. It can cause the leaves to wither and die. To manage rust, remove the affected plants and destroy them before the disease spreads.
Common Pests
The following are common pests that can attack Peck's beardtongue:
- Aphids: Aphids suck sap from the plant and can cause the leaves to curl and turn yellow. To manage aphids, introduce natural predators like ladybugs or spray the plant with a mixture of soap and water.
- Spider mites: Spider mites are tiny pests that feed on the plant's sap, causing the leaves to become speckled. To manage spider mites, increase the humidity around the plant by misting it regularly and introduce natural predators.
- Thrips: Thrips can cause the flowers and leaves to become discolored and distorted. To manage thrips, introduce natural predators or spray the plant with an insecticide approved for use on Penstemon peckii Pennell.
Preventative Measures
To prevent diseases and pests from attacking your Penstemon peckii Pennell plant, follow these preventative measures:
- Plant the Peck's beardtongue in well-draining soil to prevent root rot.
- Provide adequate spacing between plants to improve air circulation and reduce the spread of diseases.
- Water the plant in the morning to give it ample time to dry before sunset.
- Monitor the plant regularly for signs of pests and diseases.
- Introduce natural predators like ladybugs or lacewings into your garden to control pests.
With proper disease and pest management techniques, you can maintain a healthy Penstemon peckii Pennell plant that thrives in your garden.
