Dionaea muscipula 'Big Mouth'
Cultivar: Big Mouth
Dionaea muscipula 'Big Mouth' is a compact carnivorous perennial distinguished by traps that open wider than the typical species, often showing vibrant coloration. It thrives in nutrient-poor, acidic conditions, making it an excellent candidate for specialized bog gardens or controlled container environments. This plant relies on its unique snapping mechanisms to capture insects, which supplement its nutrient intake in high-light, moist conditions.
The Big Mouth Venus Flytrap is a unique cultivar prized for its remarkably large, robust traps and vigorous growth habit. This fascinating carnivorous plant is perfect for enthusiasts looking to add a distinct specimen to their collection.

Mature Plant Look
A symmetrical rosette of wide, impressive traps sitting low to the soil surface.
Mature Stage Morphology

Plant Faqs
Does the Big Mouth trap catch its own food? Yes, it captures insects to supplement its nutrients in low-nutrient soil. Do I need to feed it? No, it will capture enough insects on its own if kept in a suitable bright area. Can I use tap water? No, mineral content in tap water can damage the plant; always use distilled or rainwater.
Root Look
Fine, delicate white to light brown root system associated with a moist peat plug.
Soil Look
Dark, damp peat-based substrate often topped with light-colored perlite or sphagnum.
Starter Stage
