Schizachne Purpurascens (torr.) Swallen - False Melic

Overview of Schizachne purpurascens (Torr.) Swallen

Schizachne purpurascens (Torr.) Swallen, commonly known as purple pitted grass, is a species of grass native to North America. This perennial grass species belongs to the Poaceae family and is commonly found in wet prairies, meadows, and marshes throughout the United States.

Description of Schizachne purpurascens (Torr.) Swallen

Schizachne purpurascens (Torr.) Swallen is a small to medium-sized grass species growing up to 60 cm tall. Its leaves are thin and narrow, measuring about 5-15 cm long and 2-5 mm wide. The leaves are dark green and taper towards the end. The stem of the plant is slender and upright, with purplish nodes which gives it a distinct appearance. The inflorescence is a thin, delicate panicle which is about 5-20 cm long. The flowers are small, about 2-3 mm long and have a purple tinge to them.

Common Uses for Schizachne purpurascens (Torr.) Swallen

Schizachne purpurascens (Torr.) Swallen is primarily used for erosion control, as it has strong roots that can hold soil in place. It is also used in prairie and wetland restoration, and as an ornamental plant in landscaping. Some Native American tribes have used the plant for medicinal purposes. However, it is not commonly cultivated for commercial purposes due to its relatively low seed yield.

Conclusion

In summary, Schizachne purpurascens (Torr.) Swallen is a native grass species commonly found in wet prairies, meadows, and marshes throughout the United States. Its narrow leaves and slender purplish stem make it easily identifiable. It is primarily used for erosion control, restoration, and ornamental purposes. Despite its potential for medicinal use, it is not commonly cultivated for commercial purposes.

Light Requirements

Schizachne purpurascens grows best in a full sunlight to partial shade environment. It can handle direct sun exposure, but partial shade is ideal for optimal growth and development.

Temperature Requirements

The plant has a medium tolerance for extreme temperatures and can survive in USDA Plant Hardiness Zones 3 through 7. It thrives in moderate temperatures, between 60 and 70 degrees Fahrenheit, but is adaptable to temperatures outside of this range.

Soil Requirements

Schizachne purpurascens requires well-draining soil with moderate to high fertility. It can tolerate various soil types, including sand, loam, and clay, but prefers loamy soil with a pH range of 5.5 to 7.5. The soil should be kept consistently moist, but not waterlogged.

Cultivation Methods

Schizachne purpurascens, also known as Purple Wild-rice, prefers moist, well-drained soil and partial shade. It is a cool-season grass that thrives in cooler temperatures with low humidity. Sow the seeds in early spring (typically March or April) or late fall (typically November) when the soil is moist.

Watering Needs

It is essential to keep the soil moist throughout the growing season. Regular watering is required to keep the soil consistently moist, especially during hot, dry periods. Water the plants once the top layer of soil becomes dry, avoiding overwatering, which can cause root rot.

Fertilization

Purple Wild-rice does not require heavy fertilization. Fertilization in early spring with a balanced fertilizer (10-10-10) can be beneficial. Apply the fertilizer following the recommended rates on the package. Avoid over-fertilizing, which can burn the plants, and ensure that the plants are watered after fertilization.

Pruning

Pruning is not necessary for Purple Wild-rice. However, maintaining the height of the grass to a reasonable level can be achieved by frequently mowing the grass to a height of 4-6 inches. Mowing can also prevent the grass from spreading too much and becoming invasive.

Propagation of Schizachne purpurascens (Torr.) Swallen

Schizachne purpurascens (Torr.) Swallen, commonly known as purple reedgrass, is a cool season, perennial grass that is native to North America. It grows in moist to wet areas, such as marshes and meadows, and is an excellent plant for erosion control due to its spreading rhizomes and fibrous roots. Propagation of Schizachne purpurascens can be achieved through several methods, including seed propagation, division, and transplants.

Seed Propagation

Schizachne purpurascens can be propagated through seeds, which can be obtained through harvesting from mature plants or purchasing from seed companies. The seeds need to be stratified before sowing to break dormancy. This can be achieved by storing the seeds in the refrigerator for a period of 30-60 days before planting. Once stratified, seeds can be sown in the spring or fall in a prepared seedbed. The seedbed should be well-draining, and the seeds should be lightly covered with soil to a depth of about ¼ inch. Germination should occur within 2-3 weeks, with seedlings reaching maturity in 2-3 years.

Division

Division is another propagation method that can be used for Schizachne purpurascens. This method is best used for mature plants that have developed a clump of roots. The ideal time for division is in the spring or fall. To divide the plant, the clump should be carefully dug up, and the roots and rhizomes should be separated into smaller sections. The sections should each have a healthy root system and several stems. The divisions can then be replanted in a prepared bed with well-draining soil at the same depth as the original plant.

Transplant

Transplanting seedlings is another propagation method for Schizachne purpurascens. This method is useful when a particular variety of the plant is desired but is not available through seed or division. Seedlings can be grown in containers for the first year and then transplanted into a prepared bed in the spring or fall. When transplanting, care should be taken to not disturb the roots and to water the seedling thoroughly after planting.

Disease Management

Schizachne purpurascens (Torr.) Swallen is relatively resistant to most plant diseases. However, it may occasionally be affected by fungal leaf spots. These appear as brown or purplish spots on the leaves. To manage this, remove diseased leaves and destroy them to prevent the spread of the disease. Also, avoid overhead watering because the water droplets on leaves create a moist environment that fosters the growth of fungal spores. Finally, maintain good air circulation around the plants to reduce high humidity that can lead to fungal growth.

Pest Management

The most common pest that can affect Schizachne purpurascens (Torr.) Swallen is the grasshopper. These insects can cause significant damage to the stem and leaves of the plant by eating them. To manage grasshopper infestation, use physical barriers like netting or row covers to prevent them from accessing the plant. You can also introduce natural predators like birds, spiders, and praying mantis to control their population. Chemical control is also an option, but it should be the last resort. Use insecticides that are labeled safe for use on ornamental grasses and follow the manufacturer's instructions carefully.
