Description
Asparagus rubicundus has tufts of tiny thread-like leaves, along its spiny brown stems

This species of Asparagus grows as a thorny bush, to a height of 1,5 metres. Stems are erect, round, shiny and have a distinctive dark-brown colour.

At each node along a stem, below the branch, there is a single, recurved (max.6mm) thorn.

The numerous, tiny (3-7mm), linear-cylindrical, thread-like leaves are in feathery tufts.[3]

The young shoots of this plant are edible, like those of commercial asparagus.[4]

This species is part of a group of closely related African Asparagus species, including Asparagus lignosus, Asparagus concinnus and Asparagus microraphis.[5]

Distribution
Asparagus rubicundus in habitat, near Greyton.

It occurs throughout the southern and western Cape, as far north as Namibia, in coarse sandy, clay or granite-based soil in fynbos vegetation and coastal sand plains.
