Centratherum punctatum, commonly known as Brazilian Button Flower, is an annual plant in the Asteraceae family. It is native to seasonally dry tropical climates and is known for its vibrant purple flowers. The plant thrives in warm conditions and is often used in ornamental gardening.
Centratherum punctatum requires bright, direct sunlight for optimal growth. It prefers moderate temperatures and moderate humidity levels. Water the plant when the soil is almost completely dry, and ensure it is planted in a location that receives ample sunlight.
Soil
The plant prefers well-draining loamy soil. It is important to ensure that the soil dries out almost completely between waterings to prevent root rot. A soil mix that includes sand can help improve drainage.
Fertilizer

Repotting
As an annual plant, Centratherum punctatum does not typically require repotting. However, if grown in containers, ensure the pot has good drainage and consider repotting if the plant outgrows its container.
Propagation
Centratherum punctatum can be propagated by seeds. Sow the seeds in well-draining soil in a sunny location. The best time to propagate is during the spring when temperatures are warm.
Pruning
Pruning is not generally required for Centratherum punctatum. However, you can deadhead spent flowers to encourage more blooms and maintain a tidy appearance.
Toxicity
Centratherum punctatum is not known to be toxic to pets or humans. It is generally considered safe for gardens and households.
