Which plant is known for its bright green leaves and bluish purple flowers?

Ground ivy is known for its distinct appearance, characterized by its bright green, rounded leaves that have a slightly serrated edge and bluish-purple flowers. This plant is a perennial herb that thrives in various environments, often found in shaded and moist areas. The flowers generally emerge in the spring and early summer, adding a pop of color against its vibrant foliage.

The other plants listed have different attributes that set them apart. Knotweed, for instance, typically has upright, jointed stems and clusters of tiny white flowers. Violet is recognized for its heart-shaped leaves and can produce a range of flower colors, usually violet or purple, but does not have the same combination of leaf and flower color as Ground ivy. White clover features trifoliate leaves and white flowers, lacking the bluish hue found in Ground ivy blooms. Thus, the combination of bright green leaves and bluish purple flowers makes Ground ivy the correct choice.
