Heterotheca sessiliflora grows in many types of habitats. It is a perennial herb which is quite variable in appearance, particularly across its four subspecies. It may be a small clumping or mat-forming plant or grow tall stems to heights exceeding a meter. It is coated in small bristles or long woolly hairs and it is glandular, particularly around the inflorescence. The flower head contains long yellowish disc florets and the edge is fringed with yellow ray florets.[5]
