|Asparagus meyerii or Asparagus plumosus v. Meyerii
Full sun with lots of water during the growing season. In cool weather, it doesn't care if you water it or not.
Asparagus meyerii will make viable seeds, although they are very slow growing for the first year or two. To me, the flowers smell like peaches for the first few days.
If you put this plant up at eye level and are a loser television-watcher, you'll see why I nicknamed it 'Sideshow Bob'.
