Black Cobra chile peppers are elongated and slender, averaging seven centimeters in length, and have a conical shape that tapers to a pointed tip. The skin is firm, glossy, and smooth.

Black Cobra chile peppers are primarily harvested when the pods are black. As the pepper ripens into its striking red hue, it will further increase in spiciness.

Black Cobra chile peppers are highly ornamental plants with many pods that grow straight out from the stems, sometimes upright, and are displayed in varying stages of maturity and color. This pepper is also known for being the only variety in the Capsicum annuum species that has fuzzy stems and leaves.
