Botrychium multifidum (Gmel.) Trev. ssp. californicum (Underwood) Clausen
Botrychium multifidum (Gmel.) Trev. ssp. californicum (Underwood) Clausen, also known as the California moonwort, is a species of fern native to North America. It is a perennial herb and a member of the Ophioglossaceae family. The plant is commonly found in California, specifically in the coastal ranges and the Sierra Nevada Mountains, growing in forest clearings and open meadows.
Common Names
The California moonwort has several common names, including many-forked moonwort, leathery grape fern, and leather root. The name "moonwort" comes from the belief that the plant appears only during a full moon, while the name "leathery grape fern" refers to its oval-shaped leaves that resemble a grape cluster.
Uses
The California moonwort has been used medicinally for its astringent properties. The plant's young fronds were mashed into a pulp and used as a poultice to stop bleeding and reduce swelling. The plant was also used to treat diarrhea and dysentery. Nowadays, the plant is used mainly for its ornamental value, and it is included in rock gardens and native plant gardens.
General Appearance
The California moonwort is a small plant that typically grows up to six inches tall. It has a vertical stem that may be partially or completely buried in the soil. The fronds are compound and highly dissected, with each leaflet being divided into 3-6 segments, giving the plant a delicate and lacy appearance. The leaves are leathery and dark green in color, with a waxy surface and a slightly curled edge. The plant reproduces through spores that are released from spore-bearing structures located at the base of the leaves.
Overall, the California moonwort is a fascinating plant with an interesting history and useful properties. Its delicate beauty and hardiness make it a sought-after addition to any garden.

Cultivation of Botrychium multifidum (Gmel.) Trev. ssp. californicum (Underwood) Clausen
Botrychium multifidum (Gmel.) Trev. ssp. californicum (Underwood) Clausen is a perennial plant that can grow up to 20 cm tall. It is a native species of North America, and it is commonly found in rocky hillsides, meadows, and forests. Here are some cultivation methods that can help you have a healthy and thriving Botrychium multifidum (Gmel.) Trev. ssp. californicum (Underwood) Clausen in your garden:
Watering Needs
Botrychium multifidum (Gmel.) Trev. ssp. californicum (Underwood) Clausen requires moderate to regular watering to thrive. Keep the soil consistently moist but not too wet as it may promote fungal growth, especially during the flowering period. Ensure the soil is well-draining to prevent waterlogging, which can cause root rot. Water the plant deeply once or twice a week, depending on your location's climate and weather conditions.
Fertilization
Botrychium multifidum (Gmel.) Trev. ssp. californicum (Underwood) Clausen grows well in nutrient-rich soil. It requires regular fertilization to enhance its growth and development. Use a slow-release, balanced fertilizer to provide the necessary nutrients, including phosphorus, nitrogen, and potassium. Fertilize the plant once every two weeks during its growing season.
Pruning
Botrychium multifidum (Gmel.) Trev. ssp. californicum (Underwood) Clausen does not require a lot of pruning. However, it is advisable to remove any dead, diseased, or damaged leaves or stems to promote healthy growth. You can also prune any overgrown branches to maintain the plant's shape and size. Use clean and sharp pruning tools to avoid injuring the plant's tissues. Prune the plant during its dormancy period.
Propagation of Botrychium multifidum ssp. californicum
Botrychium multifidum ssp. californicum, commonly known as the California grapefern, is an herbaceous perennial plant native to California. It is a small fern with delicate fronds that grow up to 15 centimeters tall and produce spores for reproduction. Apart from spore germination, Botrychium multifidum ssp. californicum can also be propagated vegetatively using different methods. The following are some of the ways to propagate the plant:
Division
Division is one of the easiest ways to propagate Botrychium multifidum ssp. californicum. The rootstock of the plant forms small corms that can be gently dug up and separated from the main plant. Each corm can produce a new plant when replanted. The best time to divide the plant is during the dormant season in winter or early spring, before new growth appears.
Spore propagation
Spore propagation involves sowing the spores of Botrychium multifidum ssp. californicum in a growing medium to produce new plants. Spores are tiny, dust-like particles produced by the fertile fronds of the plant. To propagate the plant through spores, the following steps can be followed:
- Collect spores from a mature fertile frond
- Sterilize a growing medium such as sphagnum moss
- Sow the spores on the surface of the growing medium
- Cover the container with a plastic bag to maintain humidity
- Place the container in a well-lit area, but not in direct sunlight
- Wait for the spores to germinate and develop into young plants
- Transfer the young plants to individual pots or in a garden bed for further growth
Rhizome cuttings
Botrychium multifidum ssp. californicum can also be propagated through rhizome cuttings. Rhizomes are underground stems that produce roots and shoots. To propagate the plant using rhizome cuttings, the following steps can be followed:
- Dig up the plant and separate a section of the rhizome
- Cut the rhizome section into smaller pieces, each containing at least one bud and a portion of the root system
- Prepare a potting mix or garden bed with good drainage
- Plant the rhizome cuttings vertically, with the buds facing upwards and the roots downwards, in the soil
- Water the cuttings and keep the soil moist until new growth appears
Botrychium multifidum ssp. californicum is a beautiful and unique plant that can be propagated using these different methods. With proper care and maintenance, propagated plants can grow and thrive just like those grown from spores.
Disease and Pest Management for Botrychium multifidum ssp. californicum
Botrychium multifidum ssp. californicum, commonly known as California botrychium, is a fern species native to western North America. Like all plants, it can be susceptible to various diseases and pests that can cause significant harm. Here are some common diseases and pests that might affect the plant and ways to manage them.
Diseases
Botrychium multifidum smut - This fungus can cause irregular swellings or galls on the fronds of the plant. Infected fronds will eventually turn black and die. To manage this disease, remove and destroy infected fronds and avoid overhead watering that can spread the spores.
Root rot - This disease is caused by soil-borne fungi that attack the plant's roots, causing them to rot. Infected plants may appear wilted and have stunted growth. To manage this disease, improve soil drainage, avoid overwatering, and remove infected plants from the garden.
Pests
Slugs and snails - These pests can chew holes in the fronds of the plant and leave behind a slimy trail. To manage them, handpick and remove them from the garden, or use traps and baits.
Spider mites - These tiny pests can suck the sap from the plant's fronds, causing them to dry out and turn brown. To manage them, spray the plant with a strong jet of water or apply insecticidal soap.
Deer - These animals can browse on the fronds of the plant, causing significant damage. To manage them, use physical barriers like fencing or repellents to keep them away from the plant.
By practicing good plant care practices, regular monitoring, and early intervention, you can prevent or reduce the severity of diseases and pests that may affect Botrychium multifidum ssp. californicum.
