Asparagus meyeri âFoxtail Fernâ. Asparagus meyeri is an evergreen arching perennial that has feathery, needle-like, stems. Foxtail Fern is often thought of as a fern but really it is not a true fern, i.e. it produces seeds rather than spores. This âFernâ is however related to the vegetable Asparagus which also has fern-like foliage. Foxtail Fern is very similar to Asparagus Fern only its growth habit is very dense and it produces tail-like fronds for a fluffy âFoxtailâ look. In the summer the plant has small white flowers that are followed by bright red berries.
