A mound of bright-green, ferny leaves make this Asparagus a very attractive perennial. Its rapidly

growing, prickly stems trail down walls or may cover the ground, including more slow-growing

neighbours. Insignificant, fragrant, white flowers are followed by red berries, which contrast

well with the shiny, needle-like foliage. They are, however, considered poisonous. Botanical

note: the leaves are what are known as ‘cladodes’ (modified branches), while the true foliage has

degenerated to tiny inconspicuous scales. This South African native looks best in semi-shaded,

rather protected locations. For a neat appearance, good drainage and soil with added organic

matter are essential. It is drought-tolerant, but only for a short time. Fleshy roots allow a quick

recovery, when leggy stems are cut back entirely to renew the plant or when the plant has been

damaged by frost. Dividing the rootstock is the easiest propagation method or by seed. A. d.

‘Sprengeri’ has landscape value as a groundcover or foreground planting. The trailing stems are

often used in floral arrangements, and this asparagus is frequently seen as a long-lasting indoor

or pot plant on a patio. Chlorosis may be a problem in alkaline soils, but can be prevented by

an application of ammonium sulphate or iron chelate. The low-maintenance measures include

fertilising and periodic pruning.
