The leaves of sweet wakerobin are arranged in a distinctive whorl of three. These simple, ovate to broadly elliptic bracts measure 4-8 inches (10-20 cm) in both length and width. The margins are entire, meaning they are smooth without any serrations. The leaves have a rich, deep green color and a smooth texture. Their vein pattern is parallel with prominent midribs. These characteristic features are pivotal for identifying sweet wakerobin, especially given their unique whorled arrangement.

Sweet wakerobin produces striking maroon three-petaled flowers that exhibit a distinctive recurved shape, curving backward. These flowers, which nod gracefully, can reach up to 4 inches (10 cm) across and are complemented by three green sepals. Notable for their long exserted stamens and a purple ovary, these blooms emit a fetid odor. In North Carolina, you can observe these captivating flowers in their natural bloom from April to June.

The stem of sweet wakerobin is unbranched and typically green, reaching heights of 1-2 feet (30-60 cm). It exhibits a smooth texture with a slender structure, usually varying in thickness from 0.1 to 0.3 inches (2.5 to 7.6 mm). This perennial herb features a single, upright stem that arises directly from the rhizome, displaying a slight sheen under sunlight. The stem supports large leaves in a whorled arrangement, making it distinct and easily identifiable in its native habitats.

The fruit of sweet wakerobin is a distinctive berry-like capsule, consisting of six parts, which matures to a noteworthy red-maroon hue. This fruit becomes prominently available from July through August. Structurally, the capsule might catch the eye of enthusiasts due to its unique segmentation. Upon ripening, the fruit’s flesh could potentially exhibit a softer texture, which is common among berry-like fruits. The exact dimensions of the fruit are not specified, but its color and structure are signature characteristics that aid in its identification.
