Fern Moss - Thuidium Delicatulum
The Fern Moss is a perennial moss made up of compound leaves. The loosely matted evergreen leaves are green to yellowish green, with the central stems up to 8.5 cm in length. The Fern Moss prefers medium shade and will tolerate partial sun. It prefers moist, acidic soil or hummus with protection from the prevailing winds.
Fern Moss is a top choice for gardeners who want to fill in the gaps between stepping stones, cover a woodland area with a thick green carpet, or soften the edges of a wall or driveway. In fact, this tenacious moss is used as chinking for buildings in the Himalayas. Its color can vary from golden-green to bright green, depending upon growing conditions. Fern Moss is so named because when viewed up close, the tiny stems resemble fern fronds. That feathery, delicate look is paired with a terrible growing habit. Fern Moss forms dense mats of vegetation, so it's ideal as a substitute for grass in shady spots. It's not unusual for a planting of fern moss to double in size within one year. Moreover, it is easy to transplant to other areas by gently pulling up chunks of plants. It can grow in most soil types, but it prefers loamy soil and can be a challenge to grow on loose, sandy ground. It tolerates partial sun but likes shade the best and needs moisture to thrive. Fern moss can work as a ground stabilizer to slow water run-off, but it must be secured with netting when first planted to prevent it from washing away before it's established. Like all mosses, it is evergreen and will not go brown in the winter. It may become dormant in periods of low rainfall, but it will revive once it's rehydrated. That can be helped along with a regular misting of water.
