Summary
Silphium asteriscus, commonly known as Starry Rosinweed, is a deciduous perennial herb native to prairies, glades, and open woodlands in the Southeastern USA. It typically grows to a height of 2-5 feet (0.6-1.5 meters) and a width of 1 foot (0.3 meters). The plant features tall, sturdy stems topped with bright yellow, daisy-like flowers that bloom from late spring through fall, providing a long season of visual interest. The flowers are highly attractive to pollinators, adding ecological value to the garden.
Starry Rosinweed is valued for its drought tolerance and its ability to thrive in poor soils, making it an excellent choice for naturalistic plantings and wildflower gardens. It is often used in prairie restorations, as well as in borders and as a specimen plant. While it prefers full sun, it can also tolerate part shade, and it adapts well to a range of soil types, provided they have good drainage. This species is not known for significant disease or pest problems, but it can spread somewhat aggressively by seed in optimal conditions. Gardeners may wish to deadhead spent flowers to prevent self-sowing if spread is a concern.CC BY-SA 4.0
