Trichterfalle originates from Dr. König in Germany who used phytohormones in tissue culture to create it. The scaling and "funnel traps" aren't 100% stable year round, meaning that Trichterfalle also produces quite a few normal traps, but the odd traps for which the plant is named are usually produced quite a few times throughout the growing season.
In good light, Trichterfalle will develop a deep red coloration on the interior of the traps. It's a beautiful, unique and freaky flytrap clone that is highly sought after by many Venus fly trap collectors!
