Foxtail Fern. Labeled here as Asparagus densiflorus 'Myers'. This is not a true fern, rather it is related to the usual garden asparagus, being in the genus Asparagus. This is not supposed to survive frost, but could become invasive where there is no risk of frost. The correct scientific name is Asparagus aethiopicus.
