Appearance
The plant typically grows from 1-2 feet tall and as wide as 1-2 feet, forming a low, bushy mound. The flowers of the Crosswhite's beardtongue are lavender-pink with white throats and the blooms are held in dense panicles above the foliage. They bloom from late spring until midsummer and attract bees, butterflies, and hummingbirds.
Uses
P. ramosus Crosswhite is primarily grown in rock gardens and wildflower meadows. It is also an excellent choice for naturalizing, as it tends to self-seed. It is used in traditional Native American medicine to treat several ailments, including fever, pain, sore throat, and snakebite. Additionally, the plant contains medicinal properties that can be used as an anti-inflammatory and analgesic.
Light Requirements
Penstemon ramosus Crosswhite requires full sun exposure for optimal growth. The plant needs at least six hours of direct sunlight daily. Without enough sunlight, the plant may grow leggy and not produce flowers.
Temperature Requirements
This plant grows well in warm temperatures but thrives in cooler environments. A temperature range of 40 to 75 degrees Fahrenheit is ideal for its growth. It cannot tolerate frost and will die if subjected to extremely cold temperatures.
Soil Requirements
P. ramosus Crosswhite grows best in loose, well-draining soil that is rich in organic matter. A pH range of 6 to 7.5 is ideal for the plant. The soil must be moist but not waterlogged, as too much water can cause root rot. Mulching the soil around the plant can help retain moisture and provide nutrients for growth.
Cultivation Methods
Penstemon ramosus Crosswhite, commonly referred to as Crosswhite's beardtongue, is a herbaceous perennial that belongs to the family Plantaginaceae. This plant thrives in full sun or light shade and well-drained soils. Before planting, ensure that the soil is worked up thoroughly to remove any weeds or grass. This also promotes good air circulation, which is crucial for preventing fungal diseases. The soil pH should range from 6.0 to 8.0, which is slightly alkaline to neutral.
Watering Needs
Given its preference for well-drained soil, Penstemon ramosus Crosswhite requires moderate watering. During hot and dry weather, ensure that the soil is moist to a depth of at least 6 inches. This plant is drought-resistant but does better when it has sufficient water. Overwatering should be avoided as it can lead to root rot.
Fertilization
Penstemon ramosus Crosswhite is a low maintenance plant that doesn't require regular fertilization. However, applying an all-purpose granular fertilizer in early spring helps to promote healthy growth. The fertilizer can be applied around the base of the plant and worked gently into the soil. Be sure to follow the recommended application rates on the fertilizer package to avoid overfertilizing.
Pruning
Crosswhite's beardtongue doesn't require regular pruning but benefits from a little tidying up after the flowers have faded. This is particularly important for maintaining a neat appearance and promoting bushier growth. Use clean and sterilized pruning tools to cut off the stems that have already bloomed. If the plant is too tall or leggy, a hard prune can be done in early spring to encourage new growth from the base.
