Cheilanthes Takeuchii W.h. Wagner - Takeuch's Lipfern

Origin and Common Names

Cheilanthes takeuchii W.H. Wagner, also known as the Takeuchi's lip fern, is a rare and unique fern species endemic to the island of Hawaii in the United States. It was named in honor of Dr. Wataru Takeuchi, a renowned Japanese fern expert who contributed significant research on Hawaiian ferns.

Appearance

The Takeuchi's lip fern has a distinctive appearance with elegant fronds that grow up to 30 cm long and 10 cm wide. The fronds are bipinnate, meaning that the leaflet is once divided into pinnae, which are then divided into small segments. The segments are bright green and leathery with a triangular shape and slightly toothed edges. The fern's rhizome is dark brown to black and covered with small scales, which help to identify and distinguish this species from other ferns.

Uses

Although there are no known medicinal or culinary uses for Cheilanthes takeuchii W.H. Wagner, it is a cherished plant among collectors, gardeners, and enthusiasts for its aesthetic beauty. It is well adapted to grow in dry, rocky areas and tolerates full sun exposure, making it an ideal candidate for rock gardens, xeriscapes, and other landscapes that require low maintenance and water conservation.

Additionally, as one of the rarest ferns in Hawaii, the Takeuchi's lip fern is protected under state and federal laws, and it is essential to promote conservation efforts to ensure its survival and preserve its beauty for future generations.

Light Requirements

The Cheilanthes takeuchii W.H. Wagner is known to be native to areas with bright light. Therefore, it is advisable to grow it in places that receive bright light, preferably 4-6 hours of morning sun. However, it is essential to make sure that the plant does not receive direct sunlight for an extended time as it might scorch its delicate leaves.

Temperature Requirements

The Cheilanthes takeuchii W.H. Wagner prefers temperatures ranging between 10 °C to 15°C during the growing season. It is a low-temperature plant and cannot sustain high temperatures relatively well, so it is essential to avoid heat sources such as radiators and vents. Furthermore, It is essential to ensure that the temperature around the plant does not drop below 10°C as it might damage the root system and, as a consequence, the whole plant.

Soil Requirements

The Cheilanthes takeuchii W.H. Wagner is adapted to grow in rocky areas or crevices. Therefore, it is essential to provide soil that replicates its natural habitat. The soil should be ''well-draining'', as stagnated water could lead to root rot. It is advisable to use a mixture of gravel and loamy soil to create a porous soil mixture that drains well. A pH range between 6.5 and 7.5 is optimal for this plant growth.

Cultivation Methods

Cheilanthes takeuchii is an evergreen fern that thrives in areas with partial shade, such as under the canopy of trees or on rocky slopes. This plant prefers well-drained soil that is slightly acidic to neutral. It is recommended to plant the ferns in containers with drainage holes, or at the edge of raised beds to prevent waterlogging.

The best time to plant Cheilanthes takeuchii is in the spring or fall when the temperatures range between 60-70°F. Dig a hole twice the size of the plant's root ball, and add compost or well-rotted manure to the planting hole to improve soil quality. Water the ferns thoroughly after planting them.

Watering Needs

Watering Cheilanthes takeuchii can be a bit tricky, as these ferns require a well-draining soil to prevent root rot. However, they also need consistent moisture to thrive. It is best to keep the soil moist but not waterlogged. If you are growing these ferns in containers, ensure that their drainage holes are not clogged to prevent waterlogging.

Water Cheilanthes takeuchii once a week, or when the soil becomes dry to the touch. Make sure to water the ferns at the base and avoid overhead watering, which can lead to fungal diseases.

Fertilization

Cheilanthes takeuchii prefers soil that is rich in nutrients. Fertilize the ferns during the growing season, which starts in the spring and ends in the fall. A balanced fertilizer with an NPK ratio of 10-10-10 is ideal for these ferns.

Apply the fertilizer once a month, following the manufacturer's instructions. Over-fertilizing can lead to salt buildup, which is harmful to the ferns. Water the ferns thoroughly after fertilizing to distribute the nutrients evenly.

Pruning

Cheilanthes takeuchii does not require much pruning, but it is advisable to remove dead and yellowing fronds as they can harbor pests and diseases. Use a sharp pair of scissors or pruners to cut the fronds at the base, taking care not to damage the healthy fronds.

You can also divide Cheilanthes takeuchii every two to three years to propagate more plants. Gently remove the plant from its container or bed and separate the rhizomes into smaller clumps. Replant the clumps in a fresh potting mix or planting hole.

Propagation of Cheilanthes takeuchii W.H. Wagner

Cheilanthes takeuchii W.H. Wagner, commonly known as Takeuchi’s lip fern, is a species of fern native to California. If you are interested in propagating this beautiful plant, there are different methods you can follow depending on your preferences and the resources you have available.

Spore propagation

The most common way of propagating ferns is through spores, which are reproductive cells that can be collected from the underside of the fronds when they are mature. How to propagate Cheilanthes takeuchii W.H. Wagner through spores:

1. Collect mature fronds in the morning when they are dry, healthy, and full of spores.
2. Place a piece of paper or a plastic bag under the fronds and cut them off from the plant using sterilized scissors.
3. Put the fronds in a paper bag or envelope and store them for a few days to let the spores dry.
4. When the spores are dry, scatter them over the surface of sterilized potting soil in a shallow tray or container.
5. Cover the tray or container with a clear plastic lid or cling film to retain moisture and place it in a warm, bright spot away from direct sunlight.
6. After about 2-3 weeks, tiny green plants, called gametophytes, will emerge from the spores. Keep the tray or container moist at all times to promote growth.
7. When the gametophytes are big enough, carefully transfer them to individual pots with sterilized potting soil and keep them in a sheltered spot until they establish themselves.

Division

Another way to propagate Cheilanthes takeuchii W.H. Wagner is through division, which involves separating mature clumps of the plant into smaller sections that can be replanted. This method can be effective if you already have a mature plant and want to increase its quantity or size:

1. Carefully remove the plant you want to divide from its pot or bed.
2. Divide the plant by gently pulling its root ball apart into smaller sections with your hands or a clean, sharp knife or spade.
3. Inspect each section for any signs of damage or disease and discard any that don't look healthy.
4. Plant each section in clean, moist soil, and water them thoroughly.
5. Place the pots or containers in a protected spot until the plant establishes itself.

Propagation can be a fun and rewarding way to expand your collection of plants and Cheilanthes takeuchii W.H. Wagner is no exception. You can try either of the two methods above, or a combination of them, to increase the number of ferns you have and bring more green beauty into your home or garden.
