The trap of the Venus Flytrap is one of Nature's most amazing marvels. The outer edges of the two clamshell-like halves are lined with nectar glands and stout bristles.
They grow well in a standard peat moss/sand which can be anything from 50% to 70% peat moss. There's no need to fertilize, as the plant relies on insects for food.
The most well known species of carnivorous plants. Traps have a limited number of false alarms. Don't stimulate them too often. Artificially springing the trap drains the plant's energy.
