What flower color is characteristic of oxalis?

Oxalis, commonly known as wood sorrel, is characterized by its yellow flowers, which is why that answer is correct. This plant is often recognized for its clover-like leaf shapes and can produce flowers in various colors, although yellow is the most typical and prevalent in many species.

While oxalis may exhibit other colors occasionally, such as white or even red in some specific varieties, yellow remains the most common color associated with this genus. This characteristic aids in its identification, making it easier for those in horticulture and pest control to recognize and manage oxalis effectively in turf situations.
