Largest trap on a Venus flytrap

The largest individual trapping leaf from a Venus flytrap (Dionaea muscipula) is a specimen of the cultivar “GJ Montecore", which was verified to be 6.6 cm (2.59 in) across the mid-rib on 9 June 2026. It was grown in Colorado Springs, Colorado, USA, by carnivorous plant enthusiast Jeremiah Harris (USA).

This bettered the previous record of 6.1 cm (2.4 in) for a trap from a cultivar called "Alien" that was also cultivated by Harris, as measured on 7 June 2021.

There are many cultivars of the Venus flytrap and the trap size, shape and colouration varies widely. Typically, though, the snapping traps are around 2–3 cm (0.7–1.2 in) wide across the mid-rib. The cultivar "GJ Montecore" was originally bred by Mathias (Matze) Maier of Green Jaws Nursery in Germany in 2014.

Harris founded the Colorado Carnivorous Plant Society in 2003 and boasts one of the largest private collections of carnivorous plants in the USA.

The cultivar "B-52" is a favourite selection among Venus flytrap growers. In ideal conditions, it can reportedly produce trapping leaves of similar proportions to "Alien" and "GJ Montecore", and perhaps even larger, though none of these claims have yet to be formally measured and verified.
