Which summer annual broadleaf weed resembles clover and has tiny pinkish-purple flowers at each node?

The summer annual broadleaf weed that resembles clover and features tiny pinkish-purple flowers at each node is annual lespedeza. This plant is characterized by its trifoliate leaves, similar to those of clover, and its flowers typically emerge at the axils of the leaves. The pinkish-purple flowers are small and clustered, making them noticeable in the landscape.

Annual lespedeza is also an important plant for erosion control and is often used in disturbed areas. Its appearance and flowering patterns make it distinct among other types of summer weeds, allowing it to be easily identified. In contrast, large crabgrass is a grassy weed, henbit is a winter annual with distinctive whorled leaves and purple flowers, and gripeweed does not share the clover-like leaf structure or flower at the nodes like lespedeza.
