The asparagus fern plant is not really a fern at all, but a member of the Liliaceae family, making it a relative of lilies and tulips. However, care is similar to most ferns. When growing asparagus ferns inside, place them near places with humidity and indirect light. Mist regularly. Its lush and frilly foliage makes it appear soft and fuzzy, but beware that there are thorny spurs. It's toxic to humans and animals, and is commonly placed in hanging displays.
