Senecio biserratus, commonly known as Jagged Fireweed or Ragwort, is a perennial herb native to the open woodlands, meadows, and disturbed sites of Southeastern Australia. It typically grows to a height of 1-3 feet (0.3-0.9 meters) and features clusters of bright yellow, daisy-like flowers that bloom in the summer and are quite showy. The plant has an upright form and can spread to form dense colonies.

Jagged Fireweed is valued for its vibrant yellow flowers that attract pollinators such as bees and butterflies, making it a beneficial addition to wildlife gardens. It is often used in restoration projects to stabilize soil and in wildflower meadows due to its ease of maintenance and adaptability. In cultivation, it thrives in full sun but can tolerate partial shade, and prefers medium-draining soils such as clay, loam, or sandy types. It requires moderate watering but can tolerate drought once established. While generally disease-free, it can be susceptible to rust and may spread aggressively if not managed, potentially becoming weedy in favorable conditions.CC BY-SA 4.0
