Cotula Coronopifolia Aquatic Pond Plant - Brass Buttons

Cotula coronopifolia, commonly known as Brass Buttons or Buttonweed, is a low-growing perennial plant that belongs to the Asteraceae family. It is native to coastal regions of Australia and New Zealand but has naturalized in various parts of the world. Here's a detailed description and care guide for Cotula coronopifolia:

Description:
Cotula coronopifolia forms a dense mat of small, round, button-like foliage. The leaves are finely dissected, bright green, and resemble miniature fern fronds. The plant typically grows to a height of about 2-4 inches (5-10 cm) with a spread of 6-12 inches (15-30 cm). In summer, Cotula coronopifolia produces small, yellow button-like flowers on short stems that rise above the foliage. The flowers are daisy-like in appearance and add a pop of color to the plant's overall appearance.

Care Guide:

Lighting: Cotula coronopifolia thrives in full sun to partial shade. It can tolerate some shade but prefers a location with at least 4-6 hours of direct sunlight per day. In hot climates, some afternoon shade can help protect it from excessive heat and maintain its vibrant green color.

Water: Cotula coronopifolia prefers consistently moist soil conditions. It is best suited to areas with regular rainfall or where supplemental watering is available. Keep the soil evenly moist but avoid waterlogging, as this can lead to root rot. Water deeply when the top inch of soil feels dry to the touch.

Soil: Cotula coronopifolia prefers well-draining soil with a slightly acidic to neutral pH. It can tolerate a range of soil types, including sandy, loamy, or clay soils. However, it thrives in soils that retain some moisture while allowing excess water to drain away.

Temperature: Cotula coronopifolia is adaptable to a range of temperatures. It is hardy in USDA hardiness zones 7-11. It can tolerate mild frosts but may require protection in colder regions. In hot climates, provide some shade during the hottest part of the day to prevent scorching of the foliage.

Fertilizer: Cotula coronopifolia generally does not require heavy fertilization. A light application of a balanced, slow-release fertilizer in early spring can provide the plant with a nutrient boost. Follow the manufacturer's instructions and avoid overfertilization, which can lead to excessive growth and reduced plant vigor.

Maintenance: Cotula coronopifolia is a relatively low-maintenance plant. Trim back any overgrown or straggly stems to maintain a compact and tidy appearance. It can tolerate occasional light foot traffic, making it suitable for pathways or between stepping stones.

Propagation: Cotula coronopifolia can be propagated through division or by collecting and sowing its seeds. Division is best done in spring or early fall. Carefully separate the clumps and replant them in suitable soil or planting medium. Seeds can be collected from mature flowers and sown in containers or directly in the soil.

Pests and Diseases: Cotula coronopifolia is generally resistant to pests and diseases. However, it may occasionally attract aphids or be susceptible to root rot if grown in overly wet conditions. Monitor the plant for any signs of pests or diseases and take appropriate measures if necessary.

By following these care guidelines, you can enjoy the charming and low-growing nature of Cotula coronopifolia in your garden or landscape. Adjust the care routine based on your specific growing conditions and monitor the plant for any signs of stress, pests, or diseases. With proper care, Cotula coronopifolia can provide a carpet of lush, fern-like foliage and bright yellow flowers, adding a unique and vibrant touch to rock gardens, borders, or as a groundcover in moist areas.
