You are very observant. Neither of these are ferns at all but are true flowering plants. The asparagus fern, Asparagus setaceus, is a close relative of the edible asparagus and produces tiny white flowers and purplish black fruits. The numerous leaves are very small, bright green and produced on long branches.hey have varying degrees of green, dark red, and gray variegation on their fronds and, as a result, they are very popular plants in shade gardens. The variegated holly fern, Arachnoides simplicior var. variegata, has dark green fronds with a greenish yellow band running along the center of the main vein.
