For example, a decoction of this plant has been used to treat stomach problems, fever, and as a diuretic. Additionally, its roots have been used as a poultice for rheumatic pains. Nowadays, this plant is mainly used for ornamental purposes, particularly in rock gardens and alpine gardens.
Light Requirements
Pharnaceum brevicaule (DC.) Bartl. requires full sun to partial shade to grow properly. Therefore, it is recommended to grow them in a location that receives at least 6 hours of direct sunlight each day. However, the plant will also survive in areas with partial shade caused by trees or buildings.
Temperature Requirements
The plant can tolerate a wide range of temperatures, but it prefers a warm environment, with average temperatures between 21°C to 27°C. It can tolerate temperatures as low as 10°C and as high as 35°C, but frost will damage the plant significantly. When growing the Pharnaceum brevicaule (DC.) Bartl., ensure that the plant is protected from frost during the winter season.
Soil Requirements
The Pharnaceum brevicaule (DC.) Bartl. prefers a well-draining soil that is rich in organic matter. Sandy loam soil works best for the plants to thrive. The soil pH value should be within the range of 5.5 to 8.5 for optimal growth. Additionally, the soil should be moist but not waterlogged. It is important to ensure that the soil is well-drained to prevent the roots from rotting.
Cultivation methods
Pharnaceum brevicaule, commonly known as Short-stemmed Pharnaceum, is a herbaceous perennial plant native to Turkey, Georgia, and Azerbaijan. The plant prefers well-drained soils with a neutral to alkaline pH ranging between 7.0 to 8.0. It can grow in full sun or partial shade and can tolerate temperatures below freezing.
Propagation of Pharnaceum brevicaule is usually done from seeds, but it can also be propagated by division. Seeds should be sown in late winter or early spring in well-drained soil. The seedlings should be transplanted into pots once they are big enough to handle, and then moved to a permanent location in the garden.
Watering needs
Pharnaceum brevicaule requires moderate watering during the growing season. Keep the soil moist but not waterlogged, and avoid allowing the soil to dry out completely. In dry weather, it may be necessary to provide additional water. It is best to water the plant at ground level, avoiding splashing water on the leaves.
Fertilization
The plant does not require high levels of fertilizers. Lightly feeding with a balanced, slow-release fertilizer during the growing season can help to encourage healthy growth. Avoid using high-nitrogen fertilizers as this may cause the plant to produce more foliage rather than flowers.
Pruning
Pharnaceum brevicaule is a low-growing plant that doesn't require frequent pruning. However, pruning can help to keep the plant tidy and promote flowering. Deadheading, or removing the spent flowers, can encourage the plant to produce more blooms. In the fall, cut back the plant to ground level to prepare it for the winter season.
Propagation of Pharnaceum brevicaule (DC.) Bartl.
There are two commonly used propagation methods for Pharnaceum brevicaule (DC.) Bartl., which are sexual and asexual propagation. It is important to note that the seeds of the plant have a very low germination rate and require specific conditions to successfully germinate. Therefore, asexual propagation is often preferred.
Asexual Propagation
One commonly used asexual propagation method for Pharnaceum brevicaule (DC.) Bartl. is through root cuttings. The roots of the plant are cut into sections, treated with rooting hormone, and planted in a well-draining, moist soil mix. The cuttings should be kept in a warm, humid environment until roots develop, and then gradually acclimated to normal growing conditions.
Another asexual propagation method is through division of the plant. The plant can be carefully removed from its pot or growing area and divided into sections, ensuring each section has healthy roots and foliage. The divided sections can then be replanted in suitable growing conditions.
Sexual Propagation
Seeds of Pharnaceum brevicaule (DC.) Bartl. can be sown in a well-draining, moist soil mix, and kept in a warm, humid environment to aid germination. However, the germination rate of the seeds is very low, and it can take several months for seeds to germinate. Special care must be taken with seedlings to ensure they do not become diseased or damaged.
Overall, asexual propagation methods are preferred for Pharnaceum brevicaule (DC.) Bartl. due to the low germination rate of seeds. Root cuttings and division of the plant are effective propagation methods that can ensure the successful propagation of the plant.
