This introduced perennial plant is 2-7' tall. It branches occasionally and has a spindly-ferny appearance. The central stem at the base of the plant is stout and more or less round in circumference. Appressed against this stem are small alternate leaves that are scale-like and deltoid in shape. When the central stem is about 6" tall, it resembles the spears of asparagus that are sold in supermarkets. As this stem continues to lengthen, it develops alternate branches that are more narrow in circumference. Each of these branches develops whorls of filiform branchlets where the tiny scale-like leaves occur. Each branchlet is up to 1" long. The foliage of Wild Asparagus is glabrous. At the base of the whorled branchlets, there develops 1 or 2 flowers from nodding hairless stalks up to 1" long. Because Wild Asparagus is dioecious, a single plant will produce either all male flowers or all female flowers. Both types of flower are about 1/3" long and have 6 oblong tepals that are greenish white or greenish yellow. The male flowers have 6 stamens with yellow anthers, while the female flowers have a pistil with a single style. The tepals of the male flowers curve outward at their tips, resembling a little bell, while the female flowers are more cylindrical. The blooming period occurs during the late spring to early summer and lasts about 1 month. Each female flower is replaced by a single fleshy berry about 1/3" across. This berry is spheroid and glabrous, containing several seeds inside. It is initially green, but turns red when fully ripened. At the apex of the berry are remnants of the tepals. The root system produces rhizomes that are long and spreading. This plant often forms vegetative colonies.
