description

Asparagus asparagoides is a climbing , richly branched, perennial , deciduous or semi-deciduous plant with glossy green phyllocladia . Your cylindrical rhizome has numerous lateral, spindle-shaped and radially arranged root tubers . The different sized root tubers are up to 6 inches long and 2 inches wide. The sinewy, twisted shoots are smooth or furrowed and can reach a length of up to 2 meters. Side shoots are short and have pearly ribs. The phyllocladia are different in size and shape. They are ovate-pointed, up to 4 inches long and 2 inches wide, flat or folded and curved. The phyllocladia are multi-veined, but mostly with three distinct leaf veins on each side. The edge of the phyllocladia is smooth or tiny serrated.

The flower stalk, which is up to 1 centimeter long, is subdivided below the flower envelope . The tepals are up to 1 centimeter long and in the lower half form a tube that is bent back upwards. The upright stamens are bent together. Their stamens are widened below to form two small, spread out teeth. The anthers are red. The stalked, pear-shaped ovary is in a pen narrowed, which is as long as the ovary. There are up to six ovules per compartment . The short, spreading scar is eyelashed. Asparagus asparagoides blooms from mid-winter to spring.

The spherical fruits are about 1 centimeter in diameter and usually contain many seeds .

The number of chromosomes is 2n = 20.
