Kind of a name problem. Asparagus setaceus is Common Asparagus Fern. Asparagus officinalis is Wild Asparagus, although it is also the cultivated species. I think the “Common” helps Asparagus setaceus get mapped everywhere (though it’s frost sensitive). The “Wild” may encourage people to think A. officinalis can’t be the name for what they recognize as the cultivated plant even when it’s growing wild. Not sure there’s a solution, but I think these common names are part of the problem.
