Venus fly traps are perennials that form bulbs. Sometimes in shipping, a leaf or two will die back. Leaves turn black when they die back, but the bulb is still healthy.
Information below is only the potential the plant has. Each listing is for one plant. The "starter plant" you are buying is one plant actively growing in a 2 inch deep pot and is smaller than the plant pictured.
Has hinged leaves with stiff margined spines and 3 or 4 sensitive hairs in the center of each lobe. When an insect touches the hairs, the hinge mechanism is triggered, and the leaves close quite rapidly, trapping the insect.
Grow this in a terrarium or in a cool greenhouse or in a bog garden.
