Arisaema triphyllum

Jack in the pulpit

Jack in the pulpit is one of the first non-ephemeral flowers that can be seen in spring often blooming in late April into May and beyond. Unique flowers are a comprised of an outer spaeth and an inner spadix and are characteristic examples of the arum family. The plants have a tendency to change sexes, often starting their life as males producing pollen and slowly storing energy in their underground corm. In time they will switch to female and upon pollination will produce large clusters of bright red fruits using the energy stored below. After successful fruiting, they will return to the male form and begin the process all over again. Best in rich, moist soils and tolerant of a wide range of light conditions, we love pairing Jack in the pulpit with other spring bloomers such as woodland phlox, foamflower, and trillium.
