The leaves of deathcamas are basal, slender, and grass-like, emerging from the base of the plant. They can grow up to 16 inches (40 cm) in length. The foliage is long, narrow, and linear, typically featuring a bright to dark green color. The texture of the leaves is smooth, and the veins are generally parallel, running the length of the leaf, which is characteristic of monocots. This foliage provides a delicate, grass-like appearance essential for identifying the plant.

The flowers of deathcamas are arranged in open panicles, each showcasing creamy-white blooms. These flowers consist of 6 white tepals, each approximately 0.8 inches (2 cm) long, with two prominent yellow-green nectary glands near the base. The tepals form a star-shaped structure, enhancing their visual appeal. They typically bloom in late spring to early summer, giving off a subtle fragrance. This distinctive arrangement and coloration are key identifiers for deathcamas's flowers.

The stem of deathcamas is sturdy and typically green with a subtle reddish hue. It is cylindrical, with a smooth texture and can reach up to 3 feet (90 cm) in height. The stem is mostly unbranched, thickens as it grows, and supports the plant's upright structure effectively. Occasionally, the stem may display a slight sheen, enhancing its visual distinctiveness. These characteristics make the stem a key feature for identifying deathcamas in its natural habitat.

The fruit of deathcamas is characterized as a dry, round capsule exhibiting an oval shape. It typically features a beige to light brown color when mature, with a smooth to lightly textured surface. Measuring about 0.5 inches (1.3 cm) in length, these capsules often contain several tiny, black seeds that are released once the fruit splits open along the seams. The fruit's attachment to the plant is slender, allowing for easy dispersal by wind or animal interaction. Structurally, the capsule possesses small segments indicative of where the seeds reside.
