Sprenger's Asparagus

Asparagus densiflorus (among several species colloquially called asparagus ferns; no relation to actual ferns), or the foxtail fern (asparagus) or plume fern, is a variable, evergreen-perennial plant related to cultivated, edible asparagus.

It is native to southern Africa, from Mozambique to South Africa, but is widely cultivated.
