Plantain Lily vs Polypody Fern Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Plantain Lily
Hosta spp.
Hostas, commonly known as Plantain Lilies, are herbaceous perennials prized for their attractive foliage. They are primarily grown for their diverse leaf shapes, sizes, colors (ranging from shades of green, blue, and gold), and textures. Hostas typically form clumps of leaves that emerge from rhizomes. While they do produce flowers, often lavender or white, in summer, the foliage is the main attraction. They are predominantly outdoor plants, thriving in shaded gardens. Indoor cultivation is challenging due to specific light and dormancy requirements.
Polypody Fern
Polypodium virginianum
Polypodium virginianum, commonly known as Rock Polypody, is an evergreen fern typically found growing on rocks and tree trunks in moist, shaded environments. It features creeping rhizomes that anchor it to its substrate, from which arise deeply lobed, leathery fronds. These fronds are typically 10-30 cm long and have a distinctive, somewhat glossy appearance. While primarily an outdoor plant, it is sometimes grown indoors, though replicating its natural environment can be challenging. People grow it for its unique appearance and ability to thrive in rocky or woodland gardens. It is not a fast grower.
