Identifying Jack-in-the-Pulpit: A Connecticut Woodland Find

Identifying Jack-in-the-Pulpit in Your Garden

A gardener in Connecticut discovered a mysterious three-leafed plant growing among daylilies. The leaves measured about 12 inches long, and a green pod with white spots—roughly the size of a plum—appeared halfway down the stem. Concerned about potential toxicity to cats, the gardener sought identification.

Expert Identification

The plant is Arisaema triphyllum, commonly known as Jack-in-the-Pulpit. This native wildflower is considered one of the more desirable woodland species. Its distinctive flower consists of a hollow, leaf-like bract (the pulpit) that curves over a cluster of tiny, almost microscopic flowers (Jack). The structure observed is actually a cluster of developing fruit that will eventually ripen to bright red, each containing a single seed.

Toxicity and Safety

All parts of Jack-in-the-Pulpit contain calcium oxalate crystals and are technically poisonous if ingested. However, many common houseplants and landscape plants share this trait. Pets rarely consume them due to the immediate burning sensation caused by the crystals. For households with cats, the risk is low, but it's wise to discourage chewing on any plant material.

If you encounter this plant in your garden, consider it a fortunate addition to a shaded, moist area. It thrives in woodland conditions and adds unique architectural interest.
