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.
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.
Orontium aquaticum, Golden Club, or the floating Arum is a plant species endemic to the Eastern United States. Its native habitat extends from as south as Florida, to New York State. It grows in ponds, slow streams, and bogs and swamps.
The plant belongs to the family Araceae, as is clear from its inflorescence. The golden color stands out in the mostly dormant landscape of a bog in spring—Photograph taken in the New Jersey pinelands.
The plant is also called “never-wet.” As you can see here, the leaves are water repellent.
The plant has generated morphological confusion. If you are familiar with a peace lily, you would know that a modified leaf, a spathe surrounds an Arum inflorescence. The spathe is missing from the mature inflorescence. You may observe a green sheath early on in the development, which drops off as the spike matures. Engler had classified the structure as a spathe. We know now that that the small green enclosure was a sympodial leaf. The spathe is missing in this species.
