Senecio ampullaceus, commonly known as Texas ragwort or Texas groundsel, is a tall annual herb native to Texas, particularly thriving in prairies, meadows, and open, disturbed areas such as roadsides. It typically grows 8-31 inches tall and features ovate to lanceolate leaves. This species is notable for its bright yellow flower heads that bloom in early to mid-spring, attracting a variety of pollinators. The plant is covered with a mat of fine hairs on its stems and leaves, which can give it a grayish appearance. The fruit is an achene, each topped with a tuft of bristles (pappus) that aids in wind dispersal.

Texas ragwort is valued for its ability to attract pollinators and is recommended for wildflower gardens, naturalized areas, and pollinator-friendly landscaping within its native range. It is drought-tolerant and prefers full sun to part shade, thriving in sandy or well-drained soils. While it is not commonly used in formal garden settings, its ease of maintenance and bright flowers make it a good choice for informal gardens and restoration projects. Gardeners should be aware that Senecio species can contain toxic alkaloids, and Texas ragwort should not be planted where livestock graze.CC BY-SA 4.0
