Its native range can be found across tropical and subtropical regions of Africa, Asia, and Australia. It is commonly found in wet and swampy areas such as marshes, riverbanks, and floodplains.
Common Names
Ammannia baccifera L. subsp. intermedia Koehne is commonly known by various names depending on the region it is found in. In Africa, it is known as red toothcup, while in Asia, it is called India toothcup, red ammannia, and false pink baby tears. In Australia, it is known as the four-corners, and in the United States, it is called Nesaea pedicellata.
Uses
Ammannia baccifera L. subsp. intermedia Koehne has several uses in traditional medicine. In Africa, it is used to treat various ailments such as diarrhea, dysentery, and fever. In India, it is used as a natural remedy for jaundice, liver disorders, and skin diseases. The plant is also a popular aquarium plant due to its vibrant red coloration and ease of maintenance. Additionally, it can be used as a natural dye to color textiles.
General Appearance
Ammannia baccifera L. subsp. intermedia Koehne is a small aquatic plant that can grow up to 30 centimeters tall. It has thin stems that are often reddish or green in color. The plant's leaves are oval-shaped and arranged alternately along the stem. Its flowers are small and pink in color, and its fruits are small, round, and red berries. When grown in an aquarium, the plant will develop a vibrant red coloration, making it a popular choice for aquascaping.
Light Requirements
Ammannia baccifera subsp. intermedia requires moderate to high light intensity to grow properly. It thrives in well-lit areas where it receives at least 6 hours of direct sunlight daily. In an aquarium or terrarium setting, it is ideal to place the plant near a bright light source such as a fluorescent or LED lamp. Carbon dioxide (CO2) supplementation is also beneficial as it aids in photosynthesis.
Temperature Requirements
Ammannia baccifera subsp. intermedia prefers temperatures between 20-30°C (68-86°F) and can tolerate slight drops in temperature at night. In colder regions, it is recommended to place the plant in a heated environment or use a heater in the aquarium to maintain the optimal temperature range. Drastic temperature changes can cause the leaves to turn yellow and drop off.
Soil Requirements
Ammannia baccifera subsp. intermedia prefers nutrient-rich, well-aerated soils with a neutral to slightly acidic pH range of 6.5-7.5. If grown in an aquarium, a nutrient-rich substrate like aquasoil or fluorite combined with root tabs can provide the necessary nutrients for growth. In a terrarium setting, a high-quality potting mix or tropical forest soil is recommended.
Cultivation Methods
Ammannia baccifera L. subsp. intermedia Koehne is typically cultivated through seed germination. The seeds should be placed in a pot of moist soil, and kept in a warm and well-lit area. Once the seedlings are large enough, they can be transplanted to their permanent location. It is also possible to propagate the plant through stem cuttings, which should be planted in a pot of moist soil and kept in a warm and well-lit area until they root.
Watering Needs
The plant requires frequent watering, with the soil kept consistently moist. Care should be taken not to overwater the plant, as this can lead to root rot. It is recommended to water the plant in the morning or evening, as watering during the hottest part of the day can result in water loss through evaporation.
Fertilization
The plant benefits from regular fertilization with a balanced fertilizer. Fertilizer should be applied during the active growing season, with care taken to avoid overfertilization, which can lead to excessive growth and reduced plant health. It is important to follow the instructions on the fertilizer packaging to ensure the correct application rate.
Pruning
Ammannia baccifera L. subsp. intermedia Koehne benefits from regular pruning to encourage bushy growth and maintain an attractive appearance. Pruning should be carried out in the early spring, before the onset of new growth. The plant should be pruned to remove any dead, broken, or diseased branches. Pinching back the tips of the stems can also help to promote bushy growth.
Propagation of Ammannia baccifera L. subsp. intermedia Koehne
Ammannia baccifera L. subsp. intermedia Koehne is a beautiful aquatic plant that can add a touch of elegance to aquariums and water gardens. Here are some methods to propagate this plant:
Vegetative Propagation:
Ammannia baccifera L. subsp. intermedia Koehne can be easily propagated vegetatively. The plant produces side shoots that grow from the base of the stem. These side shoots can be carefully separated from the parent plant and replanted in a separate pot or in the aquarium substrate.
Cutting Propagation:
Cutting propagation is another method that can be used to propagate Ammannia baccifera L. subsp. intermedia Koehne. To propagate the plant through cuttings, use a sharp, sterilized scissor or razor blade to cut a healthy stem close to a node, or intersection where the leaf grows from the stem. The cutting should be about 3-4 inches long and should have at least one node. Plant the cutting in a substrate or potting mix that is rich in nutrients.
Seed Propagation:
Seed propagation can be a bit challenging for Ammannia baccifera L. subsp. intermedia Koehne. The plant produces small, brown seeds that are spread by water circulation in the aquarium or water garden. Collect the seeds carefully as they mature and sow them in a substrate or potting mix. The soil should be kept moist and warm to encourage germination. This method is time-consuming and requires patience as the seeds can take up to a month or more to germinate.
Overall, Ammannia baccifera L. subsp. intermedia Koehne is an easy plant to propagate through vegetative and cutting methods. Seed propagation can be challenging for beginners, but it's a great way to obtain new plants and expand your collection.
Disease Management
Ammannia baccifera is generally a hardy plant and not prone to many diseases. However, like all plants, it can be affected by certain diseases in adverse conditions. Here are some common diseases that might affect the plant and ways to manage them:
- Rust: Rust appears as yellow spots on the leaves of the plant. It can cause defoliation if not treated on time. To manage rust, remove any affected leaves and spray the plant with a fungicide containing copper sulfate or neem oil.
- Root Rot: Root rot is caused by a fungus and can occur when the soil is too wet or poorly drained. To prevent root rot, ensure proper drainage of the soil. If the plant is affected, remove it from the soil, cut off the infected roots, and plant it in fresh soil.
- Leaf Spot: Leaf spot appears as small, dark spots on the leaves. To manage leaf spot, remove and destroy any affected leaves and spray the plant with a fungicide.
Pest Management
Ammannia baccifera is not commonly affected by pests, but here are some pests that might affect the plant and ways to manage them:
- Aphids: Aphids are small, pear-shaped insects that suck the sap from the leaves, causing them to yellow and wilt. To manage aphids, spray the plant with a low-toxicity insecticide or a solution of water and dish soap.
- Spider Mites: Spider mites are tiny pests that spin webs on the plant and suck the sap from its leaves. To manage spider mites, spray the plant vigorously with water to dislodge them. You can also use insecticidal soap or neem oil to manage them.
- Thrips: Thrips are small insects that can cause leaf distortion and discoloration. To manage thrips, spray the plant with a low-toxicity insecticide or a solution of water and dish soap.
