Sarracenia purpurea ssp. venosa is a herbaceous perennial plant which forms a rosette of ascending basal leaves. The highly modified leaves are tubular in shape, swollen toward the middle, and about 3-8″ long. The interior surface of each leaf is covered with stiff bristly hairs that point downward. These hairs impede the ability of small insects to escape from the interior of the leaf. Prey fall into a watery fluid at the bottom of the leaf, where the nutrients of their decaying bodies are absorbed. Extra-floral nectaries along the upper interior and rim of each leaf often lure such insects to their doom.
Their appearance is eye catching, unusual, and exotic, generally more so than their tall brethren. They also grow in almost any environment from shade to full sun.
