There’s not a lot of fern action in my dry, sunny garden, much to my regret, but in the front garden on the north side of the house, planted in the parched gloom at the foundation line, a fern is improbably thriving behind the agaves and astelias. This frothy, arching, clumping-not-running, perfectly harmless member of the asparagus family is Asparagus virgatus.
What do all these plants have in common besides the letter A? Cast-iron natures as far as tolerating dry soil and shifting sun/shade patterns throughout the year. They probably spend more time overall in shade, which suits even the agave, A. attenuata, famous among agaves for tolerating some shade. (An Aloe marlothii recently perished, unable to handle the winter in part shade.)
And I can assure you that, although related, it is not the scary monster that most of us have learned to fear in the form of the climbing asparagus, A. scandens.

An interesting graphic quality to its stems too. I’ve never seen it look this lush before, and the clue to the improvement in its former straggly growth is that white drainspout. The small amount of rainfall we’ve had so far this winter was funneled via the new gutters and directed into downspouts, and one of the downspouts empties here. San Marcos Growers says “This plant comes from South Eastern Africa, where it typically grows along shaded waterways, so it is surprising how drought tolerant this plant is.” I can now vouch for its love of moisture as well as its drought tolerance. I would love to bulk up a big specimen in a container and see what it can do when not in sheer survival mode, as I’ve been growing it.
Typical small red berries of the asparagus family follow tiny, almost imperceptible flowers.
Unlike the ineradicable climbing asparagus, Asparagaus scandens, A. virgatus is your friend.
Plant Delights Nursery lists it in their catalogue to zone 7 and credits it for tolerating a lot more sun than I give it.
