WaterFor the Beardtongue (the most common name for Penstemon Vesuvius 'Yasius'), water thoroughly whenever the top inch of soil feels dry to the touch. Typically, this will mean watering once every week, but this can vary based on temperature and humidity conditions. Provide the plant with about 1 gallon of water evenly around the base to ensure the root system is adequately saturated. During the peak of summer, you may need to water more frequently, especially if the plant is in a container. Reduce watering in the winter months when the plant is not actively growing.
LightThe Beardtongue thrives in full sun to partial shade. For optimal growth and flowering, find a spot that receives at least six to eight hours of direct sunlight daily. However, if you are in an area with extremely hot summers, providing afternoon shade can help protect the plant from scorching.
TemperatureBeardtongue plants prefer moderate temperatures ranging from 50°F to 85°F. They can survive slightly cooler nights down to about 30°F and can tolerate heat up to around 90°F. However, the ideal growing conditions are within the moderate range where they can flourish without stress from extreme temperatures.
PruningPrune Beardtongue plants to remove spent flower spikes and encourage a second bloom. Deadheading after the first flush of flowers can promote a tidier plant appearance and improve vigor. Pruning is best done in late winter or early spring, cutting back to just above a set of new leaves or a growth node.
CleaningAs needed
SoilThe Beardtongue 'Yasius' thrives in well-drained, loamy soil with a slightly acidic to neutral pH of 6.0 to 7.0. A mix of two parts loam, one part sand, and one part compost is ideal. Ensure good drainage to prevent root rot.
RepottingThe Beardtongue 'Yasius' typically requires repotting every 2-3 years to refresh the soil and accommodate root growth. Spring is the best time for repotting this perennial.
Humidity & MistingThe Beardtongue 'Yasius' prefers moderate humidity levels but is adaptable to various conditions. It does not require high humidity and can tolerate the drier air typical of many temperate climates.

Life cycleThe life of 'Yasius' Penstemon, also known as Beardtongue, begins with germination, where seeds sprout in well-draining soil with adequate warmth and moisture. After germination, the seedlings develop into young plants with a rosette of foliage at the base and start to establish a root system. As they mature, Penstemon 'Yasius' enters the vegetative stage where the plant grows leaves and stems, but does not yet flower. The next phase is the flowering stage, during which the Penstemon 'Yasius' produces vibrant, tubular flowers that attract pollinators and are typically pink or purple in color. After pollination, the plant sets seed, which then matures and is eventually dispersed for the cycle to begin anew. Lastly, in the post-flowering stage, the plant may enter a period of dormancy, especially in colder climates, only to re-emerge in the following growing season.
PropogationPropogation time
Spring to Early Summer
Penstemon 'Vesuvius', commonly known as Beardtongue, is often propagated through basal cuttings, a method popular among gardeners. In early to mid-spring, when the plant is beginning to grow vigorously, cuttings can be taken. A healthy, non-flowering shoot should be chosen and cut just below a leaf node, typically around 2-4 inches long (5-10 cm). The lower leaves are removed and the cutting is dipped into rooting hormone powder to facilitate root development. This cutting is then inserted into a pot filled with a mixture of peat and perlite, ensuring good drainage. The pot should be placed in a warm, but not direct sunlight, environment and kept moist. Roots usually develop within a few weeks, after which the new Penstemon can be transplanted to a more permanent location.
