"Foxtail" asparagus fern. Not really a fern, but sure does look like one. This is a great plant for south FL yards (or anywhere in zones 9 to 11). In colder zones, it must be wintered indoors. Makes a beautiful, fluffy container plant. (Asparagus densiflorus Meyersii)
The foxtail fern is an evergreen drought resistant plant that needs little care and looks bright green all year long. It is also known as Asparagus Meyeri, Asparagus fern or asparagus densiflorus 'myers'.
