Scientific Name: Pinguicula 'Potosiensis'

Also known as: Potosi Butterwort, Butterwort from San Luis Potosí

Origin: Native to the San Luis Potosí region of Mexico, where it grows in limestone-rich cliffs and moist, shaded rock faces.

Pinguicula 'Potosiensis' is a compact and beautiful Mexican butterwort species or form, known for its neat rosette of soft, spoon-shaped leaves and its potential for vivid pink to reddish coloration under high light. The leaves are covered in tiny glandular hairs that secrete a sticky mucilage to trap and digest small flying insects. With its manageable size, stunning colour, and consistent growth, P. potosiensis is a favourite among collectors and growers looking for a hardy, showy carnivorous plant.

Growing Requirements

Light: Bright indirect light to filtered sunlight. Strong artificial lighting (5000–6500K) enhances coloration.

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

Watering:

• Carnivorous phase: Keep the soil consistently moist.

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

Humidity: 60–85% ideal. Provide airflow to reduce the risk of mold or mildew.

Temperature: Performs best in 16–25°C. Protect from cold drafts and avoid frost.

Feeding: Catches small insects naturally. In indoor environments, feed once a month with a tiny amount of dried bloodworms or fish flakes (no additives) if prey is limited.

Dormancy: No true dormancy. Growth may slow slightly and leaves may tighten during cooler or darker periods.

What’s Included

Plant: Small and sometimes green in colour at this stage. With proper lighting and care, it will develop its full pink tones. Mature plants typically reach 4–6 cm across.

Grow Cup: 5 cm clear plastic cup with ventilated lid to maintain humidity. Includes a protective top layer of moss or sterile media.

Medium: Low-nutrient carnivorous plant mix—moisture-retentive and breathable for optimal root health.

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

Beginner Tips

• Avoid overhead watering—wet leaves can lose their stickiness and attract mold.

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

• Ensure airflow—especially in enclosed or high-humidity setups to keep the plant healthy.
