Origin and Common Names
Asplenium ×boydstoniae, also known as Boydston's spleenwort, is a hybrid fern plant that belongs to the Aspleniaceae family. The plant is a result of cross-breeding between two other fern plants namely Asplenium platyneuron and Asplenium resiliens. It is native to North America, specifically in the southeastern states of Alabama, Georgia, and North and South Carolina. The plant is known for its unique and distinctive fronds, making it a popular choice for horticulturists around the world.
General Appearance
Asplenium ×boydstoniae is a medium to large-sized fern plant with an average height of 5-12 inches. It has dark green fronds that are divided into multiple small leaflets. The fronds are typically erect, narrow, and lance-shaped, and can reach up to 30cm long and 3cm wide. The plant is evergreen, which means it remains green throughout the year, and it does not shed its leaves during winters. Boydston's spleenwort also produces spores that grow on the underside of fronds.
Uses
The Asplenium ×boydstoniae plant is primarily used as an ornamental plant due to its unique and attractive appearance. The plant is often grown in rock gardens, woodland gardens, and as a background plant along with other ornamental plants. Boydston's spleenwort is also used in landscaping projects as it requires minimal care and maintenance once established. In addition, the plant is used for medicinal purposes, specifically for treating liver and spleen-related disorders.
In conclusion, Asplenium ×boydstoniae is a beautiful and unique fern plant with several uses and benefits. With its low maintenance requirements and hardy nature, it is a popular choice for horticulturists and garden enthusiasts, making it a must-have for any garden or landscaping project.
Light Requirements
Asplenium ×boydstoniae grows best in filtered or partial shade. Direct sunlight may damage the fronds and cause scorching. It is recommended to provide 60-80% shade in areas with hot summers.
Temperature Requirements
This plant is adaptable to a range of temperatures, but prefers warm temperatures between 60-75°F. It may survive temperatures as low as 40°F but should be brought indoors if consistent temperatures drop below 50°F. In areas with hot summers, it is recommended to keep it in a cooler, shaded area.
Soil Requirements
Asplenium ×boydstoniae prefers well-draining soil that is kept moist at all times. It should be grown in a mix of organic matter, such as peat moss or compost, and inorganic matter, like sand or perlite. The pH range should be between 5.5-7.0 for optimal growth.
Fertilizer Requirements
Fertilizer is not necessary for the growth of Asplenium ×boydstoniae. However, if the growth appears to be stunted or the fronds are turning yellow, a balanced fertilizer can be applied at half-strength every other month during the growing season.
Water Requirements
Asplenium ×boydstoniae should be kept constantly moist but not overwatered. It is best to water the plant thoroughly and then allow the soil to dry out slightly before watering again. It is recommended to use filtered or distilled water to avoid fluoride and chlorine found in tap water.
Cultivation
Asplenium ×boydstoniae is a hybrid fern that grows best in moist, rich soil with good drainage. It prefers partial to full shade and needs protection from strong winds and direct sunlight. This plant can be grown indoors or outdoors in USDA plant hardiness zones 8-11.
Watering Needs
The Asplenium ×boydstoniae plant requires regular watering to keep the soil consistently moist. Avoid overwatering, which can lead to root rot, by allowing the top inch of soil to dry out between watering. Misting the plant frequently will help to maintain the required moisture levels.
Fertilization
It is recommended to fertilize the Asplenium ×boydstoniae plant bi-weekly during the growing season with a balanced houseplant fertilizer diluted to half strength. During the dormant season, fertilize the plant once a month.
Pruning
Pruning is not typically required for Asplenium ×boydstoniae plant, but removing any yellow, brown or damaged leaves with clean scissors can help to maintain plant health. Regularly checking the plant for signs of pests and diseases and taking appropriate action, such as removing infected parts, can also help to sustain the plant's growth and health.
Propagation of Asplenium ×boydstoniae (Walt.) Short
Asplenium ×boydstoniae (Walt.) Short is a hybrid fern that is relatively easy to propagate. There are two recommended methods for propagating this plant and they include spores and clump division.
Propagation by spores
Propagation by spores is usually the preferred method due to its high success rate in generating new plants. To propagate through spores, you will need to follow the simple steps below:
- Collect mature fronds from the asplenium plant and store them in a dry paper bag for a few days until the spores have fully developed.
- Clean the spores by passing them through a sieve and discarding any debris.
- Get a shallow germination tray and fill it with a mixture of peat moss and perlite.
- Sprinkle the cleaned spores on the surface of the soil mixture and moisten the soil with a spray bottle.
- Cover the tray with a transparent plastic bag to create a humid environment for the spores to germinate.
- Place the tray in a brightly lit area, but not in direct sunlight.
- After germination, it should take about 6-8 weeks for the young ferns to reach a size suitable for transplanting.
Propagation by clump division
Propagation by clump division involves splitting apart an existing mature plant into smaller sections that can develop into new plants. The steps for propagation by clump division are as follows:
- Locate an existing mature asplenium plant and dig it out of the soil with care to avoid damaging the roots.
- Use a sharp knife or pruning shears to divide the plant into two or three equal sections.
- Ensure that each divided section contains healthy leaves and an adequate amount of root system.
- Plant each divided section into a pot with a well-draining soil mixture.
- Water the newly planted sections to keep the soil moist but not waterlogged.
- Place the newly planted sections in a spot with bright but indirect light, and ensure that the temperature is kept in a range between 60°F and 80°F.
- Within a few weeks, you should start to notice new growth on the planted sections, confirming that the propagation was successful.
Disease and Pest Management for Asplenium ×boydstoniae (Walt.) Short
Asplenium ×boydstoniae (Walt.) Short is a fern that is generally resistant to most diseases and pests. However, like any plant, it can be vulnerable to some issues.
Common Diseases
One of the diseases that can affect Asplenium ×boydstoniae is root rot, which is caused by overwatering. Symptoms include stunted growth, yellowing leaves, and wilting. To avoid root rot, make sure to water the plant only when the soil is dry to the touch and ensure good drainage. If root rot has taken hold, it may be necessary to repot the fern into fresh, well-draining soil.
Another disease that can affect Asplenium ×boydstoniae is leaf spot, which is caused by fungi. Symptoms can include brown spots on the leaves, which can spread and turn into larger blotches. Remove any affected leaves and make sure to keep the plant in a well-ventilated area with good air circulation. Removing any debris around the plant can also help keep it healthy.
Common Pests
The most common pest that can afflict Asplenium ×boydstoniae is the spider mite. Symptoms include yellowing leaves, webbing, and eventual defoliation. To manage spider mites, increase the plant's humidity by misting it regularly. You can also try wiping the leaves with a mixture of water and mild dish soap or using an insecticidal soap. If the infestation is severe, it may be necessary to prune the plant and remove any affected leaves.
An occasional pest that may attack Asplenium ×boydstoniae is mealybugs. Symptoms include white, cotton-like spots on leaves, or sticky residue. To manage mealybugs, wipe the leaves with a cotton swab dipped in rubbing alcohol, or use insecticidal soap. Make sure to monitor the plant and remove any affected leaves to prevent the infestation from spreading.
Regularly checking Asplenium ×boydstoniae for signs of disease or pest infestation, along with good cultural practices, can help ensure that the plant remains healthy and vibrant.
