What Is Yellow Jack in the Pulpit?
Yellow Jack in the Pulpit is a variation of the classic Jack in the Pulpit, known scientifically as Arisaema triphyllum. Instead of the typical green or purple hood, this plant features a yellow or yellow-green spathe (the "pulpit") that curves gracefully over a central spadix (the "jack"). This unique look makes the plant stand out in shady forest gardens and natural woodlands.
Characteristics of Yellow Jack in the Pulpit

The plant consists of three main parts:
-
Spathe: The outer, hood-like part of the flower. In this variety, it is yellow or yellow-green.
-
Spadix: The inner structure, standing like a preacher in the pulpit, often paler in color.
-
Leaves: Divided into three leaflets (hence the species name triphyllum), bright green, and large.
2. Height and Growth Habit
Yellow Jack in the Pulpit typically grows between 1 and 3 feet tall. It emerges in early spring, blooms from late spring to early summer, and then produces bright red berries in late summer or early fall.
