Encelia virginensis is a bushy, sprawling shrub reaching heights between 100 and 150 cm (40-60 inches). It has many branches, with the younger parts hairy and the older stems developing a thickened bark. The gray-green, fuzzy to hairy foliage may be sparse, appearing pale because of the presence of many small hairs on the surface. Atop many erect, hairy stems are solitary daisy-like flower heads with 11 to 21 ray florets which are generally yellow, and a center of yellow disc florets. The fruit is an achene 5 to 8 millimeters long and usually lacking a pappus.[3][4]
