Overview of Utricularia vulgaris L. p.p.
Utricularia vulgaris L. p.p., commonly known as the greater bladderwort, is a carnivorous plant species that falls under the Lentibulariaceae family. It is a widespread plant species that can be found globally in regions such as North and South America, Africa, Asia and Europe.
Physical Description of Utricularia vulgaris L. p.p.
The Utricularia vulgaris L. p.p. plant can grow up to a height of 15 to 60 cm. Its habitat can either be in water or mud that is rich in organic matter. The plant's roots are thin and can either grow to be 30 cm long or be absent. The leaf blades are usually round, and they have a diameter of between 3 and 8mm. The leafstalk can be up to 20 cm in length and has numerous small bladders that aid in capturing prey. The flower stem can grow to be 30 cm long, and the plant has bright yellow flowers measuring between 2 to 3 cm long.
Uses of Utricularia vulgaris L. p.p.
Utricularia vulgaris L. p.p. is an essential plant in the food chain of freshwater ecosystems as it serves as a source of food for invertebrates and fish. It is also used as a source of medicine, traditionally, as a herb that is used to manage inflammation, wounds, and burns.
Recent studies have identified the plant's extracts to contain compounds that help in inhibiting biological processes responsible for inflammation. The plant has also proven to be useful in bioremediation since it helps in filtering out pollutants, thereby improving the water quality in freshwater ecosystems.
Common Names of Utricularia vulgaris L. p.p.
The plant is commonly known by various names depending on the region. Some of its common names include Greater bladderwort, common bladderwort, great bladderwort, and yellow bladderwort.
Light Requirements
Utricularia vulgaris L. p.p. requires a moderate to high amount of light for optimal growth. It thrives in areas with full sun exposure and may struggle in areas with heavy shading. Partial shade may be tolerated, but prolonged periods of low light may cause the plant to weaken and eventually die off. In natural environments, Utricularia vulgaris L. p.p. is commonly found growing in ponds, marshes, and other wetland areas where it can receive ample sunlight.
Temperature Requirements
Utricularia vulgaris L. p.p. is able to tolerate a wide range of temperatures, but its growth is optimal in mild to warm environments. The ideal temperature range for this plant is between 18-28°C (64-82°F). Utricularia vulgaris L. p.p. can survive in temperatures as low as 10°C (50°F) but may go dormant during the winter months of more extreme climates. During periods of prolonged heat, the plant may require additional water to avoid desiccation.
Soil and Water Requirements
Utricularia vulgaris L. p.p. thrives in moist, nutrient-rich soils. In natural environments, it is commonly found growing in boggy areas with peaty soil. The plant can also survive in sandy or silty soil as long as it can maintain adequate moisture. Utricularia vulgaris L. p.p. is a carnivorous plant that obtains its nutrients from capturing small aquatic organisms. As such, the plant typically requires a steady source of fresh water to thrive. Stagnant water can lead to quiescence or death of the plant. In cultivated environments, it is recommended to use rainwater or distilled water to avoid the accumulation of minerals from hard tap water.
Cultivation
Utricularia vulgaris can be cultivated in damp soil, preferably a mixture of peat moss and sand in equal parts. Provide a shallow tray with water to keep the soil constantly moist.
The plant requires high humidity and temperature between 20°C and 30°C. Grow it in a greenhouse or in a bright spot indoors with good ventilation. Outdoors, it prefers a partially shaded location.
Watering Needs
Utricularia vulgaris needs to be continuously wet, but not waterlogged. Ensure that the water level in the tray is maintained and never allowed to dry out.
Also, it is essential to use only distilled or rainwater for watering, as tap water contains minerals that may harm the plant.
Fertilization
Utricularia vulgaris is a carnivorous plant, and it does not require any fertilization. It obtains its nutrients from prey that it traps in its bladders. Hence, do not attempt to provide the plant with any forms of added nutrients.
Pruning
Utricularia vulgaris does not require pruning. However, removing any dead or yellowing leaves, using sterile tools, will keep the plant looking fresh and healthy.
If any aerial stems hang over the soil, allow them to root in a separate container, and then carefully cut them from the parent plant. This procedure promotes vegetative propagation of the plant.
Propagation of Utricularia vulgaris L. p.p.
There are several methods that you can use to propagate Utricularia vulgaris, including:
Splitting
You can split mature Utricularia vulgaris plants into smaller pieces and then plant them into new containers. Ensure each section has enough roots to sustain itself, and plant them in new containers filled with a mix of peat moss and sand.
Division by offsets
Utricularia vulgaris produces offsets or "pups" on the sides of the mother plant. You can separate these offshoots from the parent plant and replant them in new pots. Ensure that each pup has enough roots to sustain itself.
Cuttings
You can obtain cuttings from Utricularia vulgaris by taking a stem cutting from the mother plant. Dip the cut end into rooting hormone powder and plant the cutting in a potting mix of peat moss and perlite. Be sure to keep the cutting moist until it has developed a strong root system.
Sowing seeds
If you can obtain Utricularia vulgaris seeds, you can sow them in a mix of peat moss and sand. Ensure that you keep the mixture moist during germination and subsequent growth, and keep the pot in a warm and sunny location.
Utricularia vulgaris can be propagated using one or more of these methods. Choose the propagation method that works best for you and your resources.
Disease Management for Utricularia vulgaris L. p.p
Utricularia vulgaris L. p.p., also known as Common Bladderwort, is generally healthy and not susceptible to many diseases. However, certain fungi and bacteria can cause diseases in these plants, such as root rot and leaf spot.
To prevent root rot, it is crucial to avoid overwatering and ensure that the soil has good drainage. If root rot occurs, remove the affected plant and sterilize the soil before planting another. Leaf spot can be treated through the use of fungicides. If your plants are infected, remove the affected leaves and apply the fungicide as directed.
Pest Management for Utricularia vulgaris L. p.p.
Common pests that may affect Utricularia vulgaris L. p.p. are aphids, slugs, and snails. If left untreated, these pests can damage the leaves and even kill the plant.
To manage aphids, light infestations can be washed off the plants with a strong jet of water, but severe cases may require the application of insecticidal soap or neem oil. To control slugs and snails, remove any hiding places in the immediate environment, such as stones or thick foliage, and use baits or traps to catch them. Copper tape can also be placed around the plant pots to repel these pests.
Regular inspections of the plants for diseases and pests are necessary for effective management. Early detection and prompt action can help to prevent widespread damage and preserve the health of your Utricularia vulgaris L. p.p. plants.
