Pinguicula ‘Tina’ is a captivating and unique carnivorous plant. Its delicate rosette of leaves effectively traps insects, offering both beauty and a glimpse into carnivorous flora.
Understanding Pinguicula Tina
Pinguicula ‘Tina’ is a hybrid, specifically a cross between Pinguicula agnata and Pinguicula zecheri. This popular cultivar, registered in 2002, is known for its vibrant flowers that can display purple streaking. The plant typically forms a compact rosette of fleshy, glandular leaves, reaching a diameter of about 4 to 6 inches (10 to 15 cm).
The leaves are light green to yellowish-green, sometimes developing reddish hues under intense light. Their texture is glandular and sticky, covered in tiny mucilage-producing glands. This mucilage acts as a natural flypaper, ensnaring small insects like fruit flies and gnats. Once trapped, digestive enzymes secreted by the glands break down the soft tissues of the prey, allowing the plant to absorb essential nutrients.
Pinguicula Tina Care Guide
Light
Pinguicula ‘Tina’ thrives in bright, indirect light. An east or west-facing window providing gentle morning or late afternoon sun is ideal. While it tolerates some direct sunlight, intense midday sun can scorch leaves.
If natural light is insufficient, supplemental LED grow lights ensure healthy growth. Insufficient light causes elongated, pale leaves, while excessive light may cause leaves to turn deep red or appear bleached.
Watering
Water quality for Pinguicula ‘Tina’ is crucial due to its sensitivity to dissolved minerals. Always use distilled water, reverse osmosis (RO) water, or rainwater; tap water often contains minerals that can accumulate and harm the plant.
The tray method is a common watering technique, where the pot sits in a shallow saucer with about half an inch of water. The plant absorbs water through its drainage holes.
Allow the tray to dry out completely for a day or two between refills to prevent stagnant water. This aerates the substrate and reduces root rot risk, especially in cooler conditions or during reduced growth.
Substrate
Conventional potting soil is unsuitable for Pinguicula ‘Tina’ due to its high nutrient content and risk of root rot. This plant requires a well-draining, nutrient-poor, and acidic substrate.
A common mix consists of peat moss or long-fibered sphagnum moss combined with perlite or horticultural sand. A popular ratio is a 50/50 blend of peat moss and perlite, offering both moisture retention and excellent drainage.
The substrate must allow for proper aeration around the roots while retaining adequate moisture, preventing both waterlogging and excessive dryness.
Temperature and Humidity
Pinguicula ‘Tina’ thrives in moderate room temperatures, ideally 15°C to 29°C (55°F to 85°F). It adapts well to typical indoor environments, making it a suitable houseplant. Consistent temperature prevents stress and promotes continuous growth.
This butterwort appreciates moderate to high humidity, generally 50% to 80%. While it tolerates lower humidity if roots are consistently moist, higher humidity maintains leaf stickiness. Increase humidity with a pebble tray or room humidifier. Good air circulation is important, as stagnant, humid air can lead to fungal issues.
Feeding
Pinguicula ‘Tina’ is self-sufficient indoors, often catching enough small insects like fruit flies, gnats, and spiders to meet its nutritional needs. Supplemental feeding is necessary only if the plant appears to be struggling or lacks insect activity.
When supplementing, offer small, live insects such as fruit flies or rehydrated bloodworms. Feed sparingly, once every two to three weeks during the active growing season. Place the insect directly onto the sticky leaf surface, ensuring it is small enough for the plant to fully digest.
Overfeeding can cause leaves to rot, and larger insects may overwhelm the plant’s digestive capabilities. Never feed human food scraps or processed foods, as these can harm the plant.
Propagating Pinguicula Tina
Propagating Pinguicula ‘Tina’ is straightforward, with leaf cuttings being the most common and successful method. Success requires a consistently moist and humid environment for detached leaves.
To take a leaf cutting, gently remove a healthy, mature leaf from the outer rosette. A clean tug at the leaf’s base, ensuring a small portion of the white stem tissue (the “heel”) comes with it, increases rooting success.
Place detached leaves on a suitable substrate, such as damp sphagnum moss, a peat and perlite mix, or a moist paper towel. Lay them flat, ensuring good contact with the moist medium.
Place the container with leaf cuttings in a warm, brightly lit location, ideally under a clear lid or in a sealed plastic bag to maintain high humidity. This prevents leaves from drying out.
Within weeks to a few months, tiny plantlets emerge from the leaf base. Once large enough to handle and with a few true leaves, they can be separated and potted individually into their regular growing medium.
Common Problems and Troubleshooting
Pinguicula ‘Tina’ owners may encounter issues, often resolved with care adjustments. Leaves losing stickiness or turning brown often signals issues with water quality, insufficient humidity, or improper lighting. Using pure water and maintaining adequate humidity restores leaf health.
During cooler months or in response to changing light cycles, Pinguicula ‘Tina’ may transition from its larger, carnivorous leaves to a smaller, more succulent rosette. This is a natural adaptation to less favorable growing conditions, during which the plant reduces its carnivorous activity. During this succulent phase, reduce watering, allowing the substrate to dry out more between applications.
Pinguicula ‘Tina’ can be affected by common houseplant pests like aphids or mealybugs. Inspecting plants regularly allows for early detection and intervention. Small infestations can be managed by gently wiping pests with a cotton swab dipped in rubbing alcohol, ensuring not to damage leaves. Fungal issues, such as rot, can occur if the plant is kept too wet without adequate air circulation. Proper drainage and good airflow prevent these problems.
