Oriental Chain Fern Woodwardia orientalis var. formosana
ABOUT
The plant known commonly as the Oriental chain fern has a distinctive and attractive look that catches the eye. The leaves, also called fronds, are long and arching, creating a graceful and feathery effect. The color of the fronds can best be described as a vivid green, imbuing a sense of freshness to wherever they grow. These fronds are made up of numerous smaller leaflets that line the central stem, giving them a ladder-like appearance often described as "chain-like," which is a characteristic feature of this fern species. What's notably striking about the Oriental chain fern are the leaflets themselves. They have a slightly serrated or toothed edge and are arranged in an alternating pattern along the central stem. During certain times of the year, the underside of the leaflets will bear reproductive structures, which are typically covered in a different color, adding a subtle but interesting contrast to the green of the leaves. Interestingly, the texture of the fronds gives off a lush, almost tropical aura, contributing to the plant's overall ornamental quality. The fern has a natural elegance and can create a feeling of tranquility and greenery, making it a favorite among garden enthusiasts who wish to cultivate a serene and natural ambience in their outdoor spaces.

WaterThe Oriental chain fern should be watered regularly to maintain evenly moist soil, especially during the growing season. Water the plant deeply once or twice a week, allowing for slight drying between waterings. Depending on the environment, this generally translates to about 1-2 gallons of water per week. Make sure not to overwater, as standing water can lead to root rot. Adjust the watering frequency during winter when the plant's water requirements decrease.
LightThe Oriental chain fern prefers bright, indirect light or partial shade. It thrives under the dappled light of larger trees or in an area that receives some morning sun followed by afternoon shade. Avoid exposing it to direct, harsh sunlight, as this can scorch the fronds and cause damage to the plant.
TemperatureOriental chain fern enjoys a warm and humid environment, thriving in temperatures between 65°F and 75°F. It can survive minimum temperatures down to about 50°F but should be protected from frost. Avoid exposing the fern to temperatures above 80°F as that can stress the plant.
PruningPruning is generally not essential for the Oriental chain fern, but you can remove dead or damaged fronds as needed to maintain the plant's appearance. The best time for pruning is in the spring as new growth begins. This helps the plant conserve energy and direct it towards the development of healthy new fronds.
CleaningAs needed
SoilThe best soil mix for the Oriental Chain Fern is one that is rich, moist, and well-draining, with a slightly acidic to neutral pH, ideally between 5.5 and 7. A mixture containing equal parts of peat, pine bark, and perlite would provide a suitable environment for healthy root growth. Regularly check the pH level and amend with sulfur or lime as necessary to maintain the ideal pH range.
RepottingOriental Chain Fern should be repotted every 2 to 3 years to refresh the soil and accommodate its growing root system. It is best to repot in the spring, just before the active growth season begins. If the plant is exceptionally large or you notice roots crowding the container, it may require more frequent repotting.
Humidity & MistingOriental Chain Fern thrives in high humidity conditions, ideally between 60% and 80%. To maintain optimum humidity levels, use a humidifier, mist the plant regularly, or set the pot on a pebble tray filled with water, ensuring that the pot does not sit directly in the water to avoid root rot.
Suitable locationsIndoor

Life cycleWoodwardia orientalis var. formosana, also known as the Oriental Chain Fern, has a typical fern life cycle that begins with spore dispersion from the mature ferns' sporangia, typically located on the undersides of the fronds. These spores germinate into a gametophyte stage, commonly referred to as a prothallus, which is a small, heart-shaped, and photosynthetic tissue that grows on moist, shaded ground. The gametophyte supports sexual reproduction, producing both male (antheridia) and female (archegonia) sex organs. Upon fertilization, a zygote is formed and subsequently develops into a sporophyte, which is the recognizable leafy fern stage. The sporophyte grows through a juvenile phase where the fronds are smaller and less divided, eventually maturing to form larger and more complex fronds capable of undergoing photosynthesis, thus supporting the growth and development of the fern. Finally, once the sporophyte is mature, it produces new fronds that bear sporangia, completing the cycle as these release spores to begin the process anew.
PropogationPropogation time
Spring-Early Summer
Woodwardia orientalis var. formosana, commonly known as the Oriental Chain Fern, is a plant that can be propagated by spores. This method is the most popular when it comes to ferns due to the absence of seeds and flowers. To propagate by spores, the process should be carried out in a controlled environment to maintain humidity and temperature. Initially, spores are collected when the sporangia on the undersides of the fronds are ripe and then sown on the surface of a sterilized peat-based or peat-perlite mixture. This surface should remain damp, and the container must be covered with a clear lid or plastic wrap to maintain a high humidity level. The environment should have a consistent temperature of approximately 70 degrees Fahrenheit (21 degrees Celsius). After a period of growth, the tiny ferns can be transplanted into individual pots to continue their development.
