Commelina benghalensis

Commelina benghalensis, commonly known as Bengal dayflower, tropical spiderwort, or wandering Jew, is a perennial herbaceous plant belonging to the family Commelinaceae. It is native to tropical Asia and Africa but has spread widely and is considered an invasive species in many parts of the world, especially in agricultural settings.

The plant has fleshy, trailing stems and oval leaves with a pointed tip. Its leaves are arranged alternately along the stem and are often covered in fine hairs. The flowers are typically blue or purple, with three petals (two larger upper petals and one smaller lower petal). The flower’s bright color makes it quite distinct. Commelina benghalensis can produce both aerial and underground flowers and seeds, which makes it particularly hard to control once established. It thrives in disturbed areas like fields, roadsides, and gardens, often competing aggressively with native and cultivated plants. Its ability to root easily from stem segments allows it to spread quickly. In agricultural settings, C. benghalensis can be challenging to control due to its resilience and regenerative ability. Manual removal, consistent tillage, and certain herbicides can help manage its spread, although it often requires persistent effort to fully eradicate. This plant can be problematic in crops such as cotton and soybeans, where it competes for resources and can reduce yields. Due to its invasiveness, it is often considered a noxious weed in many agricultural regions.
