Pycnosorus globosus, commonly known as Billy Buttons, is a perennial herb that is often treated as an annual in cultivation, native to a variety of habitats including grasslands, open woodlands, and alpine regions of Southeastern Australia. It typically grows to a height of 1-3 feet (0.3-0.9 meters) and a width of 1-2 feet (0.3-0.6 meters). This plant is characterized by its spherical, bright yellow flower heads that bloom in spring and summer, which are highly attractive to both gardeners and pollinators. The foliage is narrow and grass-like, providing a fine-textured contrast in garden settings.

Billy Buttons are valued for their unique, globe-shaped flowers that make excellent cut flowers and are often used in dried floral arrangements. They are easy to grow and maintain, making them suitable for a wide range of garden styles, including rock gardens, borders, and as a part of native plantings. In cultivation, they prefer full sun exposure and well-drained soils. While they tolerate a range of soil types, they do best in sandy to loamy soils. Billy Buttons are relatively drought-tolerant once established but will benefit from regular watering during prolonged dry periods. They are not known to have significant disease or pest issues, but can be affected by root rot if overwatered or planted in poorly drained soils.CC BY-SA 4.0
