Propagation of Penstemon discolor Keck
Penstemon discolor Keck is a popular plant among gardeners due to its vibrant blue to purple flowers and its ability to thrive in different types of soils, from dry to moist. The plant is native to North America and can be propagated through different methods, including:
Propagation by Seeds
Seeds are the most common method of propagating Penstemon discolor Keck, and they can be collected from mature plants after the first flowering season. The seeds should be cleaned, dried, and stored in a cool, dry place until the next planting season. The seeds can be sown directly in the garden bed during the fall or early spring, or they can be started indoors in seed-starting trays several weeks before the last frost date.
For best results, plant the seeds in well-draining soil, cover them with a thin layer of soil, and keep them moist until germination. The ideal temperature for germination is 60-70 degrees Fahrenheit. Once the seedlings have grown to a mature size, they can be transplanted outdoors in the desired location.
Propagation by Cuttings
Penstemon discolor Keck can also be propagated by stem cuttings taken during the summer. Cut a stem that has not yet flowered and remove the lower leaves. Dip the end of the stem in rooting hormone powder and plant it in well-draining soil in a pot or a garden bed. Place the cutting in indirect sunlight and keep it moist until roots develop. This can take several weeks. Once the roots have developed, the stem cutting can be transplanted into the desired garden location.
Propagation by Division
Propagation by division is another method of producing new Penstemon discolor Keck plants. It involves separating the plant's roots and replanting them in individual pots or in a garden bed. This method is best suited for established plants that have outgrown their current location. Carefully dig up the root ball and separate it into sections, ensuring that each section has several healthy roots and a good amount of foliage. Replant each section in well-draining soil and water regularly until it takes root.

To manage this disease, avoid overhead watering and prune affected leaves. Also, apply a fungicide that contains neem or potassium bicarbonate to control the spread of powdery mildew.
- Crown Rot: This is a fungal disease that affects the base of the plant. Crown rot appears as a blackened, mushy crown, and it can be caused by overwatering or poorly draining soil. To manage this disease, avoid overwatering and try to improve soil drainage. Remove affected plants to prevent the spread of crown rot.
- Rust: This fungal disease causes orange or rust-colored spots on the leaves. Rust can weaken the plant and, if left untreated, lead to plant death. To manage this disease, remove infected leaves and apply a fungicide that contains copper or sulfur. Also, avoid overcrowding plants and provide adequate air circulation.
Common Pests
Some common pests that can affect Penstemon discolor Keck include:
