Overview:
Pellaea glabella Mett. ex Kuhn ssp. simplex (Butters) A. & D. Löve is a fern species of the family Pteridaceae that is commonly found in rocky outcrops, talus slopes, and open woodlands in Western North America.
Common Names:
Pellaea glabella Mett. ex Kuhn ssp. simplex is commonly known as the smooth cliffbrake or smooth rockfern.
Appearance:
The smooth cliffbrake plant has a dark green, glossy, and triangular blade with a length of 10-40 cm and a width of 1.5-7.5 cm. The frond is pinnate and divided into triangular segments or pinnae, which are further divided into smaller lobes. The sori (spore-bearing structures) are round and located on the underside of the frond, covered by a thin, kidney-shaped indusium. The smooth cliffbrake is a small fern with a short creeping rhizome.
Uses:
The smooth cliffbrake is not commonly used for medicinal purposes. However, the fern is used in landscaping for its attractive dark green color and glossy texture. It is also used to stabilize soils due to its hardiness and the ability to adhere to rock surfaces, making it ideal for erosion control. Additionally, some Native American tribes used it for basket weaving and tanning hides.

It is best to grow these plants in areas with a temperature range of 40 °F to 70 °F (4 °C to 21 °C).
Soil Requirements
Pellaea glabella Mett. ex Kuhn ssp. simplex (Butters) A.& D. Löve grow best in well-draining, slightly acidic, rocky, or sandy soil with good moisture retention capacity. These ferns cannot tolerate clayey soil types that hold onto water for prolonged periods, causing root rot. The ideal pH range for cultivating these ferns is between 5.5 and 7.0. Compost and sand can be added to heavy soil to improve its drainage ability. These plants require moist but not waterlogged soil, so it's best to avoid over-watering them.
Cultivation
Pellaea glabella Mett. ex Kuhn ssp. simplex (Butters) A.& D. Löve, also known as Smooth cliffbrake, is a fern plant that can be cultivated both indoors and outdoors. It is native to the western region of North America, particularly in California and Oregon, and thrives well in rocky cliffs, crevices, and canyons. When cultivating this plant, it is essential to provide a suitable environment that mimics its natural habitat.
For indoor cultivation, the plant requires a well-draining soil mixture that is rich in organic matter and a container with drainage holes. You can place the container in a bright area with indirect sunlight and maintain a temperature range of 60-80°F. For outdoor cultivation, you can plant the fern in a rock garden or a well-draining soil that is slightly acidic, preferably with a pH range of 5.0-6.5. Ensure that the plant gets enough sunlight but not direct sunlight, and protect it from strong winds.
Watering Needs
The Smooth cliffbrake plant requires moderate watering that mimics its natural habitat. You can water the plant weekly or biweekly depending on the environmental conditions. The soil should be moist but not waterlogged, and the topsoil should be allowed to dry out before the next watering. During the winter months, you can reduce the frequency of watering to prevent root rot.
Fertilization
To promote healthy growth, you can fertilize Pellaea glabella Mett. ex Kuhn ssp. simplex (Butters) A.& D. Löve with a balanced fertilizer mixture every two to three months during the growing season. You can use a liquid or granular fertilizer that is rich in nitrogen, phosphorus, and potassium. The fertilization process should coincide with watering to ensure the nutrients are well distributed.
Pruning
Pruning is an essential aspect of cultivating Pellaea glabella Mett. ex Kuhn ssp. simplex (Butters) A.& D. Löve. The plant usually grows in a clumping pattern, and pruning helps to maintain an attractive shape and prevent overcrowding. You can use clean pruning shears to cut off any dead, damaged, or yellowing fronds. Removing dead or dying fronds help the plant to conserve energy and focus on growing new healthy fronds.
Propagation Methods for Pellaea Glabella Mett. ex Kuhn ssp. Simplex (Butters) A.& D. Löve
Pellaea glabella Mett. ex Kuhn ssp. simplex (Butters) A.& D. Löve, also known as the Butter Fern, is a species of fern that is native to western North America. The plant can grow up to two feet tall and prefers to grow in rocky areas and cliffs. If you want to propagate this plant, there are several methods you can consider.
Spores
One of the most common methods of propagating Pellaea glabella is through spores. The plant produces spores on the underside of its fronds, which look like small brown dots. To collect spores, you need to find a mature frond with some spores and place it in a paper bag. The spores will eventually fall off the frond and accumulate at the bottom of the bag.
To propagate the spores, you need to create a spore bed. This can be done by mixing one part perlite or sand with one part peat moss. You should also add some lime to adjust the pH level of the mixture to about 6.5. Create a shallow container with drainage holes, fill it with the mixture, and sprinkle the spores on top. Cover the container with plastic wrap to keep the humidity levels high and place it in a warm location with strong indirect lighting. The spores will germinate and grow into small ferns over several months.
Division
Another method of propagating Pellaea glabella is through division. This method can only be applied to mature plants that have developed a rhizome. In early spring, carefully dig up the plant and cut the rhizome into sections using a sharp knife. Each section should have at least one frond and a portion of the rhizome. Plant the divided sections in a soil mixture that is well-draining and has a high organic content. Water the newly planted ferns well and keep them in a shaded area until new growth appears, then gradually move them into brighter light.
Cutting
Propagation of Pellaea glabella can also be achieved through cuttings, but this method is less common than spore propagation or division. To take a cutting from the plant, use a sharp knife or pair of scissors to cut off the frond near the base of the plant. Remove the bottom half of the frond and dip the cut end in rooting hormone, then plant it in a soil mixture that is well-draining and has a high organic content. Water the cutting well and keep it in a shaded area until it establishes roots and starts producing new growth.
By following these methods, you can propagate Pellaea glabella Mett. ex Kuhn ssp. simplex (Butters) A.& D. Löve and enjoy the beauty of this fern in your garden or home.
