Asparagus densiflorus is an extremely versatile perennial, evergreen plant that can be used as a groundcover or container plant in full sun or light shade. Although there are many striking and beautiful South African Asparagus species, most of them have horrendously large or sharp spines. A. densiflorus has only very small, hardly noticeable spines and is an excellent garden plant.

Asparagus densiflorus grows in most soils and is fairly drought tolerant, but does much better in soil which is rich in organic matter and is watered regularly. To rejuvenate the plants, they can be cut back after flowering. At this time a thick mulch of compost can be spread around the plants.

When they are grown in shade they become long-stemmed with a wide distribution of the leaves. When grown in full sun, the plants become much more sturdy and dense.

They can be readily propagated by separating the tubers in fairly large clumps, or by sowing the seed in spring or early summer.

These plants form large cushions with long, arching stems more or less densely covered with dark green, needle-like leaves.

The so-called leaves are not true leaves at all, but are actually cladodes and are thought to be modified branches, while the spines are formed from modified branches or from modified leaves.

Asparagus densiflorus flowers are small, most often white or pale pink and are very sweetly scented. The flowers are not very noticeable, as they are half hidden by the foliage and do not last long. They flower for about two weeks during the summer season, in South Africa as well as in the Northern Hemisphere. The flowering of the plants can be rather erratic, with the plants having a good flowering year on average only once every three years.
