Origin
Pellaea occidentalis (E. Nels.) Rydb. ssp. simplex (Butters) Gastony, commonly known as the western cliffbrake, is a fern species that is native to western North America. This plant can be found growing in dry rocky areas, cliffs, and open woods, from sea level to the subalpine regions of the western United States and western Canada.
Common Names
The Pellaea occidentalis (E. Nels.) Rydb. ssp. simplex (Butters) Gastony is also known by various common names, including the western cliff brake fern, simple cliff brake, and giant cliff-brake. The plant owes these names to its native region and its unique physical features.
General Appearance
The western cliffbrake is a perennial fern that typically grows in large, dense clumps with fronds extending outward. The fronds can grow up to 70 cm in length and are light green when they first emerge, then dark green as they mature. The fronds have an oblong shape and are deeply lobed into numerous smaller leaflets. The leaflets are slightly curved and finger-like in shape with toothed edges. The fern's spores are produced on the undersides of the fronds, which have a distinctive yellow-brown color and are covered in tiny dots. The roots, or rhizomes, are long, woody, and dark brown.

The Pellaea occidentalis (E. Nels.) Rydb. ssp. simplex (Butters) Gastony plant has some medicinal uses. Indigenous peoples used the fern for treating various ailments, including stomachaches, arthritis, and respiratory illnesses. Additionally, this plant can be used as an ornamental plant in gardens and landscaping due to its unique physical features and attractive foliage.
In summary, Pellaea occidentalis (E. Nels.) Rydb. ssp. simplex (Butters) Gastony is a perennial fern native to western North America. It is commonly known as the western cliffbrake, simple cliff brake, or giant cliff-brake. The fern typically grows in large, dense clumps with deeply lobed fronds that have numerous smaller leaflets. The plant's spores are produced on the undersides of the fronds, which have a distinctive yellow-brown color and are covered in tiny dots. The underground rhizomes are long, woody, and dark brown. The fern has some medicinal uses and is sometimes used as an ornamental plant in gardens and landscaping.Light Requirements:
Pellaea occidentalis ssp. simplex is a plant that requires exposure to adequate sunlight in order to grow. The ideal light requirement for this plant is partial shade, where it receives about 2-4 hours of direct sunlight per day. If the plant is exposed to too much sunlight, it can result in leaf scorching and drought stress.
Temperature Requirements:
The plant is native to western regions of North America, including the Pacific coast, Sierra Nevada, and Great Basin. It can tolerate a wide range of temperatures, ranging from as low as 15°F to as high as 100°F. Preferably, the plant grows in areas with temperatures between 60°F and 80°F, and it can withstand frost.
Soil Requirements:
Pellaea occidentalis ssp. simplex grows best in well-draining soils with slightly acidic to neutral pH levels between 5.5 and 7.5. The soil should have good aeration and be rich in organic matter. The plant can grow in a variety of soil textures, from sandy to loamy. However, it prefers moist soils that are well-draining but do not completely dry out.
Cultivation
Pellaea occidentalis (E. Nels.) Rydb. ssp. simplex (Butters) Gastony is a great addition to any garden. It is a low-maintenance plant that is easy to cultivate and can be grown indoors or outdoors. When selecting a location to plant this fern, ensure that the area receives partial shade to full sunlight and has well-draining soil. The plant thrives in sandy loams and rocky soils with a pH of about 6 to 7.5.
Watering Needs
The fern requires moderate watering to keep the soil moist but not waterlogged. Experts recommend watering the plant once a week, but this can change depending on the surrounding climate, the size of the container or pot, and the season. Ensure that the plant receives enough water to keep the soil moist, but avoid drowning it since overwatering can lead to root rot. To avoid wetting the leaves, it is best to water from the base of the plant.
Fertilization
The plant does not require constant fertilization, but applying some nutrient-rich fertilizers once per month during the growing season can enhance its growth. Experts recommend using slow-release fertilizers to avoid over-fertilizing and burning the roots. Also, it's necessary to maintain the plant's pH level to ensure the fern remains healthy and disease-resistant.
Pruning
Pellaea occidentalis (E. Nels.) Rydb. ssp. simplex (Butters) Gastony does not need frequent pruning since it grows at a moderate pace. However, removing yellowed or dead leaves regularly enhances the plant's aesthetics and encourages new growth. When removing the affected fronds, ensure that you cut them off as close to the base of the plant as possible without damaging other surrounding leaves. You can also use a pair of sterile pruning shears to prevent the spread of diseases to other plants.
Propagation of Pellaea occidentalis (E. Nels.) Rydb. ssp. simplex (Butters) Gastony
Pellaea occidentalis (E. Nels.) Rydb. ssp. simplex (Butters) Gastony, commonly known as the Sierra Cliffbrake, is a fern that is native to western North America. It is a low-maintenance plant that is tolerant of a wide range of growing conditions, making it a popular choice for gardeners and landscapers. Propagating this plant can be done through spores or division.
Propagation via spores
Propagation via spores is a common and relatively easy way to propagate the Pellaea occidentalis. The spores are typically produced in the late summer to early fall on the underside of the fronds. To collect spores, choose fronds that are mature and have turned brown. Place the frond into a paper bag and allow the spores to naturally fall into the bag. You can then sow the spores onto moist soil or a potting mix, cover the container with a clear lid and keep the container in a bright, warm location. The spores should begin to germinate in several weeks.
Propagation via division
Division is another method of propagating Pellaea occidentalis, and this technique is typically used to create new plants from well-established clumps. Begin by loosening the soil around the clump with a garden fork or shovel. Gently lift the clump out of the soil and use a sharp knife or garden shears to divide the clump into smaller sections, making sure that each section has a healthy rhizome and several fronds. Transplant the newly divided sections into their own containers or directly into the ground, and keep the soil moist until new growth appears.
Disease Management:
Pellaea occidentalis ssp. simplex is a robust and hardy plant that is not susceptible to many diseases. However, certain diseases such as fungal infections and bacterial diseases can still occur. The best way to manage these diseases is by ensuring proper plant hygiene, and using appropriate fungicides and bactericides whenever necessary.
Gray Mold (Botrytis cinerea) is a common fungal disease in Pellaea occidentalis ssp. simplex. It usually occurs when the plant is in high humidity or poor air circulation. To manage this disease, you can prune or remove infected leaves, maintain good air circulation, and avoid over-watering.
Bacterial Blight (Pseudomonas syringae pv. syringae) is another disease that can affect Pellaea occidentalis ssp. simplex. It causes blackening of the fronds, and the plant may wilt and die. To manage this disease, you can use copper-based bactericides, avoid over-irrigation, and practice good plant hygiene.
Pest Management:
Pellaea occidentalis ssp. simplex is not commonly affected by pests. However, certain pests can still affect the plant. Spider mites, scales, and mealybugs can damage the plant and restrict its growth. To manage these pests, the following strategies can be helpful:
Spider Mites (Tetranychus urticae) are a common pest that affects Pellaea occidentalis ssp. simplex. The mites can cause yellowing and loss of leaves. To manage this pest, the plant can be washed with water to remove the mites and sprayed with insecticidal soap, horticultural oil, or neem oil.
Scale Insects (Hemiptera) can also be a problem for Pellaea occidentalis ssp. simplex. They can cause leaves to wilt and die. To manage this pest, you can physically remove them by hand, prune infested plant materials, and spray the plant with insecticidal soap or horticultural oil.
Mealybugs (Pseudococcidae) can also damage the plant, leading to yellowing, wilting, and stunted growth. To manage this pest, you can physically remove the mealybugs by hand, rinse the plant with water, and use insecticidal soap or neem oil.
