In this article, we’ll delve into the world of penstemon, exploring their characteristics, growth habits, and the art of dividing and propagating these stunning plants.
Understanding Penstemon
Before we dive into the process of splitting penstemon, it’s essential to understand the characteristics and growth habits of these plants. Penstemon are perennials that typically grow between 1-3 feet tall, with some species reaching heights of up to 6 feet. They have a clump-forming habit, with leaves that are often lance-shaped and pointed. The flowers, which are the main attraction of penstemon, are tubular in shape and come in a range of colors, including pink, purple, red, white, and yellow.
Types of Penstemon
There are over 250 species of penstemon, each with its unique characteristics and growth habits. Some of the most popular species include:
Penstemon digitalis, also known as foxglove penstemon, which produces white or pale pink flowers with a distinctive bell shape.
Penstemon eatonii, a drought-tolerant species with bright red flowers and a compact growth habit.
Penstemon strictus, a tall, upright species with purple flowers and a rigid stem.
Growing Conditions
Penstemon are relatively low-maintenance plants that thrive in well-draining soil and full sun to partial shade. They prefer slightly acidic to neutral soil pH and can tolerate a range of temperatures, from -20°F to 90°F. With proper care, penstemon can live for 5-10 years, making them a long-term addition to any garden.
Can You Split Penstemon?
The answer to this question is yes, you can split penstemon. In fact, dividing and propagating penstemon is a great way to share plants with friends, increase your stock, and maintain the health and vigor of your existing plants. Splitting penstemon can be done in several ways, including division, layering, and cuttings.
Division
Division is the most common method of splitting penstemon. This involves carefully digging up the entire plant, gently separating the roots, and replanting the separated sections. The best time to divide penstemon is in the spring, when the plants are actively growing, or in the fall, about 6-8 weeks before the first frost.
To divide penstemon, follow these steps:
Dig around the plant, making sure to get as much of the root system as possible.
Gently separate the roots, taking care not to damage them.
Replant the separated sections, making sure the crown (where the roots meet the stem) is level with the soil surface.
Water well and provide adequate care, including full sun, well-draining soil, and regular watering.
Layering
Layering is another method of splitting penstemon, although it’s less common than division. This involves bending a stem down to the ground, securing it with a rock or a U-shaped wire, and covering the stem with soil. Over time, the buried stem will develop roots, and you can cut it from the parent plant and replant it.
Cuttings
Taking cuttings is a quick and easy way to propagate penstemon. This involves cutting a section of stem, removing lower leaves, and planting it in a pot filled with well-draining soil. Keep the soil moist and provide adequate light, and you should see roots develop within a few weeks.
Benefits of Splitting Penstemon
Splitting penstemon has several benefits, including:
Rejuvenating old plants: Over time, penstemon can become congested and less vigorous. Splitting them can help restore their health and vigor.
Increasing plant stock: By dividing and propagating penstemon, you can increase your plant stock and share plants with friends.
Improving plant performance: Splitting penstemon can help improve their performance, as the separated sections will have more room to grow and receive adequate light and nutrients.
Common Mistakes to Avoid
When splitting penstemon, there are several common mistakes to avoid, including:
Dividing plants that are too small: Make sure the plants are at least 2-3 years old and have a well-developed root system before attempting to divide them.
Not providing adequate care: After dividing, make sure to provide the separated sections with adequate care, including full sun, well-draining soil, and regular watering.
Dividing plants at the wrong time: The best time to divide penstemon is in the spring or fall, when the plants are actively growing or dormant.

What is Penstemon and why is it popular among gardeners?
Penstemon, also known as beardtongue, is a genus of flowering plants that are native to North America. They are popular among gardeners due to their stunning flowers, which come in a variety of colors, including pink, purple, red, and white. Penstemon plants are also relatively low-maintenance and attract pollinators, such as bees and hummingbirds, making them a great addition to any garden. With proper care, Penstemon plants can thrive in a variety of conditions, from full sun to partial shade, and can tolerate a range of soil types.
In addition to their beauty and ease of care, Penstemon plants are also popular among gardeners because they are relatively long-lived and can be divided and propagated to create new plants. This makes them a great investment for gardeners who want to create a beautiful and thriving garden without breaking the bank. By dividing and propagating Penstemon plants, gardeners can share them with friends and family, or use them to create new garden beds and borders. With the right techniques and care, Penstemon plants can be a beautiful and sustainable addition to any garden.
Can you split Penstemon plants, and if so, how?
Yes, Penstemon plants can be split, and it’s a great way to propagate new plants and keep existing ones healthy and thriving. To split a Penstemon plant, start by digging up the entire plant, taking care not to damage the roots. Then, gently separate the roots and stems, making sure each section has at least one growing tip, or “eye.” This will help ensure that the new plant will grow and thrive. It’s also a good idea to split Penstemon plants in the spring or fall, when the weather is cooler, to minimize stress on the plants.
When splitting Penstemon plants, it’s also important to trim back the stems and foliage to about half their height. This will help the plant conserve energy and reduce stress as it establishes itself in its new location. After splitting and trimming the plant, replant the new sections in well-draining soil and water them thoroughly. Keep the soil consistently moist, but not waterlogged, and provide the plants with plenty of sunlight and fertilizer. With proper care, the new plants should thrive and produce beautiful flowers in the next growing season.
What is the best time to divide and propagate Penstemon plants?
The best time to divide and propagate Penstemon plants depends on the climate and region you live in. In general, it’s best to divide and propagate Penstemon plants in the spring or fall, when the weather is cooler and there is ample moisture in the soil. This will help minimize stress on the plants and give them the best chance of success. In areas with hot summers, it’s best to avoid dividing and propagating Penstemon plants during the summer months, as this can cause the plants to become stressed and vulnerable to disease.
In areas with cold winters, it’s also important to divide and propagate Penstemon plants in the spring, after the last frost, to give them enough time to establish themselves before the winter. By dividing and propagating Penstemon plants at the right time, gardeners can help ensure their success and enjoy beautiful flowers and foliage for years to come. Additionally, dividing and propagating Penstemon plants can help to maintain their health and vigor, as it allows gardeners to remove any dead or diseased tissue and encourage new growth.
How often should I water my newly divided Penstemon plants?
After dividing and propagating Penstemon plants, it’s essential to keep the soil consistently moist, but not waterlogged. The frequency of watering will depend on the climate, soil type, and weather conditions. As a general rule, water newly divided Penstemon plants when the top inch of soil feels dry to the touch. This will help the plants establish a strong root system and prevent them from becoming stressed.
It’s also important to avoid overwatering, as this can lead to root rot and other problems. Check the soil regularly, and adjust your watering schedule accordingly. In hot, dry weather, you may need to water your Penstemon plants more frequently, while in cool, rainy weather, you may need to water them less often. By keeping the soil consistently moist, you can help your newly divided Penstemon plants thrive and produce beautiful flowers in the next growing season.
Can I grow Penstemon plants from seed, and if so, how?
Yes, Penstemon plants can be grown from seed, but it’s a more challenging and time-consuming process than dividing and propagating established plants. To grow Penstemon plants from seed, start by sowing the seeds indoors 8-10 weeks before the last frost. Use a high-quality seed starting mix and keep the soil warm and moist. Once the seeds have germinated, transplant them into individual pots and keep them in a sunny, cool location.
When the weather warms up and the danger of frost has passed, transplant the seedlings into their permanent location in the garden. Keep the soil consistently moist and provide the plants with plenty of sunlight and fertilizer. It may take several months for the seedlings to mature and produce flowers, but with proper care, they should thrive and become beautiful, blooming plants. Keep in mind that Penstemon plants grown from seed may not produce flowers that are true to the parent plant, so if you want to preserve the exact characteristics of a particular cultivar, it’s best to divide and propagate established plants.
