Arum italicum

Arum italicum, commonly known as Italian arum or Italian lords-and-ladies, is a perennial plant belonging to the family Araceae. It is native to the Mediterranean region but has been introduced to many other areas, including North America and parts of Asia, where it sometimes becomes an invasive species.

Description

Arum italicum is characterized by its glossy, arrow-shaped leaves that emerge in the autumn, survive through the winter, and die back in the spring. The plant produces a spadix surrounded by a pale green spathe, which is often streaked with white or pale purple. The spadix gives rise to a cluster of bright red berries in the summer, which are toxic to humans and animals.

Habitat and Distribution

Originally from the Mediterranean, Arum italicum has a preference for shady, moist areas. It is commonly found in woodlands, hedgerows, and garden areas. Due to its attractive foliage and berries, it has been widely cultivated and has escaped into the wild in many regions outside its native range.

Cultivation and Uses

While Arum italicum is primarily grown for its ornamental value, it is important to note that all parts of the plant are poisonous if ingested. The plant prefers shaded areas and well-drained soil, making it a popular choice for woodland gardens and shaded borders.

Toxicity

All parts of Arum italicum contain calcium oxalate crystals, which can cause severe irritation to the mouth, throat, and gastrointestinal system if ingested. The bright red berries are particularly attractive to children but should be avoided due to their high toxicity.

Conservation Status

Although Arum italicum is not currently listed as endangered, its spread in non-native areas can pose a threat to local flora. Efforts to control its spread in areas where it is considered invasive are ongoing.
