Scientific Name: Pinguicula 'Weser'

Also known as: Weser Butterwort

Origin: A well-known hybrid of Pinguicula ehlersiae × Pinguicula moranensis, originally created in Germany. Now one of the most widely grown Mexican butterwort hybrids worldwide.

Pinguicula 'Weser' is a striking and easy-care hybrid that forms a neat, flat rosette of rounded leaves. Under bright light, the foliage turns a vivid pink, often with green or white tones remaining near the center. The leaves are covered in tiny glandular hairs that produce sticky droplets to trap small flying insects like fungus gnats. Loved for its rich coloration, compact form, and reliability, 'Weser' is a top choice for beginners and experienced growers alike.

Growing Requirements

Light: Bright indirect light or filtered sun. Thrives under LED grow lights (5000–6500K).

Water: Use only distilled, rainwater, or reverse osmosis (RO) water.

Watering:

• Carnivorous phase: Keep the soil consistently moist but not soggy.

• Succulent phase: Allow the top of the soil to dry slightly between waterings.

Humidity: 60–85% preferred. Provide light airflow to reduce the risk of fungal issues.

Temperature: Performs best between 16–25°C. Protect from frost or extreme heat.

Feeding: Naturally catches small flying insects. Indoors, feed with crushed dried bloodworms or fish flakes once a month if needed.

Dormancy: No true dormancy. May slow down or produce more compact leaves in cooler months.

What’s Included

Plant: Small and sometimes green in colour at this stage. With strong light, it will develop its full pink coloration. Mature size is typically 5–8 cm across.

Grow Cup: 5 cm clear plastic cup with ventilated lid to maintain humidity during shipping. Top layer includes moss or sterile medium for protection.

Medium: Low-nutrient, moisture-retentive carnivorous plant soil—airy and suitable for strong root development.

Instructions: Step-by-step planting and care guide included.

Beginner Tips

• Avoid overhead watering—to protect the leaf’s sticky surface.

• Use only mineral-free water—tap water can cause salt buildup and root damage.

• Provide airflow—essential in high humidity environments to prevent mold and mildew.
