The leaves of fleabanes are abundant, often overlapping and forming a dense, lush cover. At the base, there's a rosette of spoon-shaped leaves, measuring approximately 2-4 inches (5-10 cm) in length and 1-2 inches (2.5-5 cm) in width. These leaves have rounded tips and smooth or slightly serrated edges. The upper surface is covered with fine hairs, giving it a slightly rough texture. The color is a vivid green with a prominent vein pattern, providing a distinctive characteristic for identification.

Fleabanes flowers are characterized by their striking appearance, featuring a showy display with vibrant yellow centers. The petals, typically white to light purple, are thin, delicate, and radiate outward in a daisy-like arrangement. Each flower measures around 0.5 to 1.5 inches (1.2 to 3.8 cm) in diameter. They often appear clustered together, creating an eye-catching mound of color. Blooming primarily in spring and summer, these flowers emit a subtle, pleasant fragrance that attracts pollinators.

The stems of fleabanes are well-branched, exhibiting a combination of textures with some sections being smooth while others are covered with fine hairs. The stem's color ranges from green to slightly reddish-brown, adding to its distinguishing features. Typically, they are moderately thick, measuring around 0.2 to 0.5 inches (0.5 to 1.3 centimeters) in diameter. These characteristics are critical for identifying fleabanes and differentiating it from similar species.

The fruit of fleabanes is characterized by a cypsela, a type of non-fleshy, single-seeded dry fruit typical to the Asteraceae family. Bearing a striking resemblance to a miniature dry seed, it boasts a pale light brown hue. A distinctive feature of this fruit is the pappus, which presents as an array of fine, hair-like structures, typically functioning in seed dispersal via wind. This tuft of light brown hairs envelops the cypsela, enhancing its dispersal potential through the air. The texture is dry and papery, and while size may vary, it is generally small and lightweight, facilitating its spread across considerable distances.
