Common Names
Psoralea psoralioides (Walt.) Cory var. eglandulosa (Ell.) Freeman's common names include eastern prairie fringed orchid, orchid psoralea, and fringed prairie orchid. The plant's common names refer to its habitat, as this species is often found in prairies or open fields, and its flowers resemble orchids with fringed edges.
Uses
Psoralea psoralioides (Walt.) Cory var. eglandulosa (Ell.) Freeman is not known for any significant economic or medicinal uses. However, the plant plays a critical role in the ecosystem and is considered an indicator of a healthy prairie ecosystem. Additionally, this plant species provides an exquisite ornamental value, and it's often included in wildflower gardens, and naturalized landscape designs.
General Appearance
Psoralea psoralioides (Walt.) Cory var. eglandulosa (Ell.) Freeman is a perennial herb with a long taproot that aids in anchoring the plant in the soil and allows it to survive harsh environmental conditions such as drought. The plant's stem is usually hairless, and the leaves are smooth to the touch with an elliptical shape. The plant's flowers are small, pink, and lavender-colored that bloom from June to July. In addition, this plant stands out due to its striking, fringed flowers that have a delicate look and resemble orchids.
Light Requirements
Psoralea psoralioides var. eglandulosa is a sun-loving plant, and it prefers full sun exposure. This plant requires at least six hours of direct sunlight each day to grow and thrive. It does not do well in shaded areas.
Temperature Requirements
The optimum temperature range for Psoralea psoralioides var. eglandulosa is between 60°F and 90°F. Temperatures above 95°F can cause heat stress to the plant, while temperatures below 50°F can cause it to die. This plant can tolerate a wide range of temperatures, but it grows best in warm and temperate climates.
Soil Requirements
Psoralea psoralioides var. eglandulosa grows well in well-draining soils. This plant prefers slightly acidic to neutral soils (pH between 6.0 and 7.0). It also requires soils rich in organic matter, which help to retain moisture and nutrients. Sandy loam soils are ideal for this plant, but it can grow in a variety of soil types, including clay loam, silt loam, and sandy soils.
Cultivation Methods
Psoralea psoralioides var. eglandulosa is a perennial plant that grows well in well-draining soils in the full sun. The plant grows best in areas that have a minimum temperature of about 50°F (10°C). The plant needs protection from severe winter conditions such as prolonged freezing temperatures.
Watering Needs
Psoralea psoralioides var. eglandulosa does not require much watering, and overwatering can cause root rot, which may ultimately lead to the death of the plant. It is advisable to let the soil dry before watering the plant again. During the hotter months, it may be necessary to water the plant every two weeks.
Fertilization
Although the plant can grow in poor soils, it will flourish when fertilized with a slow-release granular fertilizer that is high in phosphorus. Apply the fertilizer at the beginning of the growing season, and water it in thoroughly.
Pruning
The plant needs little pruning, but if necessary, cut back the woody and dead stems during early spring before the emergence of new growth. Pruning is essential in maintaining the shape of the plant and removing any diseased or damaged portions. After pruning, dispose of any debris to prevent the spread of diseases and pests.
Propagation of Psoralea psoralioides (Walt.) Cory var. eglandulosa (Ell.) Freeman
Psoralea psoralioides (Walt.) Cory var. eglandulosa (Ell.) Freeman, commonly known as Eglandulose Prairie Clover, is a herbaceous, perennial plant that belongs to the family Fabaceae. It is native to North America and can be found in the central United States. Propagation of this plant can be done using either sexual or asexual methods.
Sexual Propagation
Sexual propagation of Psoralea psoralioides (Walt.) Cory var. eglandulosa (Ell.) Freeman is done through the use of seeds. The seeds can be harvested from the plant once they are mature. They can then be planted in a well-prepared seedbed during the fall. This allows the seeds to undergo the process of stratification, which can increase their germination rate. Additionally, the seeds can be soaked in water overnight to help soften the seed coat and enhance the chances of germination. After planting, regular irrigation is required until the seedlings become established.
Asexual Propagation
Asexual propagation of Psoralea psoralioides (Walt.) Cory var. eglandulosa (Ell.) Freeman can be done through division. This method involves separating the plant into smaller sections, each with their roots attached. It is advised to use a sharp tool to prevent any damage to the plant. The separated sections can then be planted in a well-prepared soil medium, ensuring that each section is planted at a depth equivalent to its original position. The new plant will require regular irrigation until it becomes established.
Disease Management
Psoralea psoralioides (Walt.) Cory var. eglandulosa (Ell.) Freeman is relatively resistant to diseases. However, the plant may face two significant problems:
- Leaf Spots: The plant may develop some leaf spots due to fungal infections. To manage this issue, remove infected leaves, improve air circulation around the plant, and avoid overhead watering. In severe cases, consider using a fungicide such as copper-based products.
- Crown Rots: Crown rot is a serious disease caused by fungal pathogens. Allow the soil to dry between watering and do not overwater the plant to prevent the disease from spreading. Also, avoid planting in poorly-drained soil.
Pest Management
Psoralea psoralioides (Walt.) Cory var. eglandulosa (Ell.) Freeman is mostly pest-free. However, the plant may occasionally face some challenges:
- Spider Mites: Spider mites may attack the plant during drought conditions. These tiny pests suck on the plant sap, causing yellowing and wilting of leaves. Consider using a miticide to manage this problem.
- Leafhoppers: Leafhoppers may also feed on the plant during hot and dry spell, causing brown leaves. Use an insecticide if the infestation is severe. Otherwise, maintain proper watering and avoid water stress.
