Summary

Arisaema triphyllum, commonly known as jack-in-the-pulpit, is a herbaceous perennial plant native to moist woodlands, swamps, and floodplains of eastern North America. It typically grows 30–65 centimeters (12–26 inches) tall, with trifoliate leaves and a unique flowering structure: a spadix (jack) enclosed by a striped, hood-like spathe (pulpit). The flowers, which bloom in spring, are not particularly showy but are intriguing due to their unusual form. This species is known for its corm, which can be used like a root vegetable when properly cooked to neutralize its irritating calcium oxalate crystals.

Jack-in-the-pulpit is valued for its distinctive appearance and its ability to thrive in shady, moist conditions, making it a popular choice for woodland gardens and naturalized areas. It is also appreciated for its low maintenance requirements once established. In cultivation, it prefers part to full shade, consistent moisture, and well-draining soil rich in organic matter. While generally disease-free, it can suffer from root rot if the soil is too wet. Gardeners should be aware that all parts of the plant are toxic if ingested raw.CC BY-SA 4.0
