Selaginella, commonly known as blue star fern or moss fern, is a fascinating plant that often confuses people due to its unique characteristics. While its common name suggests it is a fern, Selaginella is actually classified as a moss. Let’s delve into the reasons behind this classification and explore the distinguishing features of this beautiful plant.
One of the main reasons Selaginella is classified as a moss is its low-growing and spreading habit. Unlike ferns, which typically have erect or arching fronds, Selaginella has a prostrate growth pattern. It creeps along the ground, sending out runners and forming dense mats of foliage. This growth habit is more reminiscent of mosses, which also grow close to the ground and spread horizontally.
Another characteristic that supports the classification of Selaginella as a moss is its delicate, fern-like foliage. The leaves of Selaginella are small, scale-like, and arranged in a spiral pattern along the stems. They have a feathery appearance, with each leaflet having a fine, lacy texture. This fern-like foliage is one of the reasons why Selaginella is a popular choice for terrariums and shady gardens, as it adds a unique texture and visual interest.
However, it’s worth noting that Selaginella does share some similarities with ferns. Both mosses and ferns are non-flowering plants and reproduce via spores. Selaginella produces spores in structures called sporangia, which are located on the undersides of its leaves. These spores are released into the environment and can germinate to produce new plants.
In terms of care, Selaginella thrives in shady or partially shaded locations. It prefers moist, well-draining soil and benefits from regular watering to maintain its lush appearance. However, it’s important to avoid overwatering, as excessive moisture can lead to root rot. If grown in containers or hanging baskets, it’s advisable to use a well-draining potting mix and allow the soil to dry slightly between waterings.
I have personally grown Selaginella in both outdoor garden beds and indoor terrariums, and I must say it is a delightful plant to have. Its iridescent blue foliage adds a touch of whimsy and tranquility to any space. I have found that it thrives in the dappled shade of tall trees and creates a beautiful ground cover. In terrariums, it provides a lush, verdant backdrop for other plants and brings a sense of tranquility to the miniature ecosystem.
Selaginella is a fascinating plant that is classified as a moss due to its low-growing, spreading habit and delicate, fern-like foliage. While its common name may suggest it is a fern, its growth pattern and reproductive characteristics align more closely with mosses. Whether you choose to cultivate Selaginella in your garden, containers, or terrariums, it is sure to add a touch of enchantment with its iridescent blue foliage and unique texture.
