Pycnosorus chrysanthus, commonly known as Billy Buttons or Golden Drumsticks, is a perennial herb native to various habitats in Australia, including grasslands, open forests, and alpine regions. It typically grows at a moderate rate to a height of 1-2.5 feet (0.3-0.8 meters) and a width of 1-1.5 feet (0.3-0.5 meters). This plant is characterized by its spherical, bright yellow flower heads that bloom in the summer and are quite showy, attracting pollinators and adding a splash of color to the landscape. The foliage is narrow and grass-like, providing a fine-textured contrast to the bold flowers.

Billy Buttons are valued for their unique flower form and vibrant color, which make them excellent choices for cut flower arrangements, rockeries, and as a feature in drought-tolerant gardens. They are also used in native plantings and as an informal border in garden settings. This plant prefers full sun to part shade and thrives in medium or fast-draining loam or clay soils. It is relatively low maintenance, requiring medium amounts of water once established. While generally pest-free, it can be susceptible to root rot in poorly drained soils.CC BY-SA 4.0
