Ferns are known as the epitome of undergrowth plants, thriving naturally under the towering trees of our forests. Blue star fern (a.k.a. Phlebodium aureum) is in a fern family called Polypodiaceae and is native to the tropical forests of South America. Characteristic of its family, in nature, blue star fern travels by rhizomes up the trunks of trees, making it an epiphyte like so many of our favorite houseplants. Its finger-like frond shape, bold venation, and blue coloring add interesting visual texture to any foliage collection.
