Origin
Penstemon pseudospectabilis M.E. Jones ssp. typicus Keck is a species of flowering plant in the family Plantaginaceae, commonly known as the Grand Mesa penstemon. This plant is native to the western United States, specifically found in western Colorado and eastern Utah. It is commonly found in alpine and subalpine meadows, rocky slopes, and cliffs.
Common Names
The Grand Mesa penstemon has several common names, including Grand Mesa beardtongue, Maroon penstemon, and Little Red Riding Hood.
Uses
The Grand Mesa penstemon has been traditionally used by Native American tribes for medicinal purposes. The plant is believed to have anti-inflammatory properties and can be used to treat digestive issues, kidney problems, and headaches. The roots were also used to make a tea to treat colds and coughs.
Today, the Grand Mesa penstemon is primarily used as an ornamental plant, popular for its stunning deep maroon flowers that bloom in late spring to early summer. It is also a useful plant in landscaping, as it is drought-tolerant and attracts hummingbirds and butterflies to gardens.
General Appearance
The Grand Mesa penstemon is a perennial herb that can grow up to 30 cm in height. It has smooth, lance-shaped leaves that are green and slightly wrinkled. The flowers are tubular in shape, approximately 2.5 cm long, and grow in clusters at the end of the stem. The flowers are deep maroon, with a white throat and yellow stamens. The plant has a strong taproot, which helps it survive in dry environments.
Light Requirements
Penstemon pseudospectabilis M.E. Jones ssp. typicus Keck typically grows in full sun to partial shade conditions. In ideal conditions, this plant enjoys at least six hours of direct sunlight per day. However, it is also known to tolerate some shade, making it a versatile option for different garden locations.
Temperature Requirements
The Penstemon pseudospectabilis M.E. Jones ssp. typicus Keck requires a temperate climate for optimum growth. This plant species can tolerate frost. It is hardy in USDA zones 6 through 8 and prefers temperatures between 55 and 75 degrees Fahrenheit. Extreme heat may cause the plant to wilt, and excessively cold temperatures may damage the roots.
Soil Requirements
The Penstemon pseudospectabilis M.E. Jones ssp. typicus Keck thrives in soil that is well-drained and moist. It cannot withstand soil that is too wet or too dry. A soil pH between 6.0 and 8.5 is ideal for this plant. If necessary, amend the soil with organic material to improve drainage, aeration, and water-retention capabilities.
Cultivation
Penstemon pseudospectabilis M.E. Jones ssp. typicus Keck is a perennial herb that can grow up to two feet tall and two feet wide. It is native to rocky slopes and hillsides in the southwestern United States. The plant prefers well-draining soil and full sun exposure.
Penstemon pseudospectabilis M.E. Jones ssp. typicus Keck is best propagated from seed. The seeds should be sown in the fall or spring and should be lightly covered with soil. Germination can take two to three weeks. Once the seedlings have grown enough, they can be transplanted outdoors.
Watering
Penstemon pseudospectabilis M.E. Jones ssp. typicus Keck requires regular watering during the growing season. The soil should be kept moist but not waterlogged to avoid root rot. During the winter months, the watering can be reduced as the plant goes into dormancy.
Fertilization
Penstemon pseudospectabilis M.E. Jones ssp. typicus Keck does not require regular fertilization. However, a slow-release fertilizer can be applied in the spring to encourage growth. Over-fertilizing can lead to leggy plants and reduced flowering.
Pruning
Penstemon pseudospectabilis M.E. Jones ssp. typicus Keck should be deadheaded regularly to promote continued flowering. In the fall, the dead stems and foliage can be cut back to the ground to encourage new growth in the spring. Pruning should be done carefully to avoid damaging the plant.
Propagation of Penstemon pseudospectabilis M.E. Jones ssp. typicus Keck
Penstemon pseudospectabilis M.E. Jones ssp. typicus Keck, also known as the Kachina Penstemon, can be propagated using different methods:
Seed Propagation
One of the easiest ways to propagate Penstemon pseudospectabilis is through seeds. The seeds can be planted during the spring or fall in a well-draining potting mix. Before planting, it is recommended to refrigerate the seeds for 4-6 weeks to aid in germination. Cover the seeds lightly with soil, keep them moist, and place them in a bright location.
Cuttings
Penstemon pseudospectabilis can also be propagated through stem cuttings during the growing season. Take a cutting that is 3-4 inches long and remove any leaves except for a few on the top. Dip the cutting in rooting hormone and insert it into a potting mix. Keep the mix moist and in a bright location until roots start to form.
Division
Another method to propagate Penstemon pseudospectabilis is through division. This is best done during the spring or fall. Dig up the plant and gently separate the roots into smaller sections. Replant the smaller sections in a new location or potting mix. Water the divisions regularly until they are established.
Disease Management
While Penstemon pseudospectabilis M.E. Jones ssp. typicus Keck is generally resistant to most diseases, it can be susceptible to fungal leaf spots and root rot. The use of fungicides is not recommended as a preventive measure due to the plant's potential for harm. Instead, gardeners should start with proper site selection and cultural practices. Plants should be spaced apart to allow for adequate air circulation, and watering should be done at the base of the plant to avoid getting foliage wet. Mulching can help prevent fungal spores from splashing up onto the plant. Infected leaves should be removed promptly and disposed of to prevent further spread of the disease. Application of copper-based fungicides may be necessary if the disease is severe.
Pest Management
Penstemon pseudospectabilis M.E. Jones ssp. typicus Keck is generally not bothered by pests. However, aphids and spider mites can sometimes infest the plant. The use of pesticides is not recommended as these can also harm beneficial insects and pollinators. Instead, gardeners should use natural predators such as ladybugs, lacewings and syrphid flies to control these pests. Additionally, regular spray of water can help reduce populations of these pests. If infestation is severe, application of insecticidal soap or neem oil may be necessary.
