Arisaema triphyllum (Jack-in-the-pulpit)

This common long lived perennial grows in the eastern half of the United States. Its flowers are varied in color but are hard to miss. Its three petal leaves means it can be confused with a young poison ivy. The plant itself contains Oxalic acid and oxalate crystals that can burn if ingested.

The flowers emerge after the leaves in late spring to early summer. The striped spathe surrounds a fleshy spadix that bears tiny flowers pollinated by small flies. In late summer the plant produces red berries. Its attractive flowers and large trifoliate leaves should make this an excellent addition to anybody shady garden. The plant is easy to grow in shade in the state of New Jersey.

Calla palustris (Bog Arum)

Continuing with Araceas from New Jersey, today, we look at the Wild Calla. Not to be confused with the plant Calla Lily (Zantedeschia) commonly found in garden centers. They belonged to the same family (Calla), but after further analysis, the tropical species are now classified in the genus Zantedeschia.

Bog Arum grows in the cold temperate regions of the northern hemisphere. In the Americas, it grows in the northeastern United States in bogs, swamps, and slow-moving streams.

It flowers in an inflorescence on a spadix surrounded by a white spathe.

These flowers are some of the few plants that are also pollinated by snails (not pictured).

The fruits are red berries that contain several seeds. Shown here is a developing set of berries.

The plant is very poisonous due to due to its high concentration of oxalic acid,
