The outside of the spathe is the color of dark chocolate, and the inside, milk white and as smooth as marble. Its hood sweeps up to an arrogant point, exposing its sumptuous white lining and the thick blunt spadix, which is also milk white. This plant produces two leaves per tuber, one leaf with three lobes and one with five. Sometimes they are mottled with silver, which makes them very handsome, at least until the plant goes dormant in summer.

A favorite of children, Jack-in-the-pulpit is a tuberous perennial producing one or two leaves, each divided into three narrow leaflets. But it's best known for its spring to early summer display of hooded, green spathes—Jack's pulpit—which are often striped with purple. Autumn brings clusters of densely packed, showy red berries.
