Origin and Common Names
Eriocaulon septangulare Withering var. parkeri (B.L. Robins.) Boivin & Cayouette, also known as Parker's pipewort, is a plant species endemic to North America. The species' specific epithet "septangulare" means "seven-angled", referring to the shape of its stems. The name "Parker's pipewort" honors the American botanist, Charles Pike Parker.Appearance
Parker's pipewort is a perennial monocotyledon plant species that typically grows in wet, sandy, or rocky habitats like the shores of lakes, rivers, or ponds. It has a narrow basal rosette of leaves and about 30 to 50 slender, erect stems that grow up to 40 cm in height. Its stems are stiff, wiry, and bear small, scale-like leaves typical of Eriocaulon. The species has brownish-gray inflorescences or flower heads that are globose, with a diameter of 3 to 5 mm. The flower heads are arranged in cyme-like clusters (a group of flowers with a central growing point), and each head has several inconspicuous flowers at its center, surrounded by a few sterile bracts (modified leaves).Uses
Parker's pipewort has no known medicinal uses, but its native habitat makes it an essential component of freshwater ecosystems. It provides shelter and breeding grounds for some fish species, and its root systems help stabilize stream banks and prevent erosion. It is also an attractive ornamental plant for water gardens, providing a unique texture to a pond's edge and can serve as a model organism for the study of wetland plant communities in ecology.Light

The plant grows well in temperatures ranging from 20°C to 30°C. It can tolerate slightly lower temperatures but cannot survive extreme cold. Eriocaulon septangulare Withering var. parkeri does best in warmer, tropical climates.
Soil Requirements
The plant prefers wet and boggy soils with high levels of organic matter. The soil should be well-drained, as standing water can lead to root rot. Good soil pH ranges from 5.5 to 6.5. It is suggested to add a layer of sand to the soil to provide aeration and prevent compaction.
Cultivation Methods
Eriocaulon septangulare Withering var. parkeri (B.L. Robins.) Boivin & Cayouette requires specific conditions for its cultivation. It prefers a substrate rich in nutrients and acidic PH, around 5.5 to 6.5. The plant does well in slightly cooler water, so it’s best to keep the aquarium's temperature around 70°F to 75°F. The plant needs around 10 hours of light every day, so keep it well-lit, preferably with LED lights, and reduce light intensity for 2-3 hours during the day.
Watering Needs
Water plays a significant role in the growth of Eriocaulon septangulare Withering var. parkeri (B.L. Robins.) Boivin & Cayouette. Constant exposure to water and feeding with CO2 is necessary for the plant's proper growth. The plant also prefers soft, acidic water, so adding some peat moss to the aquarium's substrate can help stabilize the pH. Ensure that the aquarium's water is free from toxic chemicals such as chlorine, and keep the water temperature within the range of 70°F to 75°F.
Fertilization
Eriocaulon septangulare Withering var. parkeri (B.L. Robins.) Boivin & Cayouette needs specific fertilization. It requires a regular intake of essential nutrients for proper growth. The best way to provide these nutrients is through liquid fertilizers that contain essential minerals such as iron, magnesium, and nitrogen. The frequent feeding of CO2 is also recommended, as it helps the plant absorb and regulate nutrients more efficiently. Ensure that you follow the instructions on the fertilizers closely to avoid overfeeding or underfeeding the plant.
Pruning
Eriocaulon septangulare Withering var. parkeri (B.L. Robins.) Boivin & Cayouette requires frequent pruning, mainly to remove any dead or decaying parts of the plant. It also helps to promote the growth of side-shoots that can later develop into healthy shoots. Regular pruning will also ensure that the plant is developing properly and not overshadowing other plants in the aquarium. Also, keep an eye out for any discolored, yellow, or brown leaves and remove them as soon as possible to avoid spreading diseases to other plants.
Propagation of Eriocaulon septangulare Withering var. parkeri
Eriocaulon septangulare Withering var. parkeri (B.L. Robins.) Boivin & Cayouette, commonly known as Parker's pipewort, is a rare and beautiful aquatic plant that is endemic to North America. It is a member of the Eriocaulon family, which includes about 400 species of freshwater and coastal plants. Parker's pipewort has attractive green foliage and a unique spray of white flowers that appear during the summer months. It is an ideal plant for water gardens, ponds, and aquariums.
Propagation by Seed
The best way to propagate Parker's pipewort is by seed. The plant produces small, brown, spindle-shaped seeds that are about 0.5 to 1 mm long. The seeds can be collected from the plant in the fall, after they have ripened and turned brown. The seeds should be sown as soon as possible because they lose viability rapidly.
To sow the seeds, fill a container with moist soil, and sprinkle the seeds on top of the soil. Do not cover the seeds with soil because they require light to germinate. Place the container in a sunny location, and keep the soil moist. Germination should occur within 2 to 3 weeks. When the seedlings have developed several leaves, they can be transplanted into their permanent location.
Propagation by Division
Parker's pipewort can also be propagated by division. This is best done in the spring or early summer, when the plant is actively growing. Carefully dig up the plant using a shovel or garden fork, and gently separate the clumps of roots and stems. Each clump should have several healthy stems and a good root system. Replant the clumps at their desired location, and keep the soil moist until the plant becomes established. Division is a good way to increase the size of a plant or to share it with friends and other growers.
Propagation by Cuttings
Parker's pipewort can also be propagated by stem cuttings. This method is more challenging and less reliable than seed or division, but it is still worth trying. Take a stem cutting that is about 4 to 6 inches long, and remove the lower leaves. Dip the cut end of the stem in rooting hormone, and plant it in moist soil. Cover the pot with a plastic bag to create a humid environment, and place it in a shaded area. Keep the soil moist, and check the cutting regularly for signs of growth. If successful, the cutting should develop roots within a few weeks, and can then be transplanted into its permanent location.
