What invasive species has clover-like shaped leaves with purple buds?

The invasive species known for having clover-like shaped leaves with purple buds is indeed Kudzu Vine. This plant is characterized by its distinctive trifoliate leaves, which resemble those of clover, and its purple flowers that bloom in clusters. Kudzu is highly invasive, spreading rapidly across various landscapes, which can lead to significant ecological disruptions including outcompeting native plant species for resources.

The other options do not share these specific features. Wild Vetch typically has more elongated leaves and different flowering characteristics. The Japanese Honeylocust is a tree and has compound leaves, while the Butterfly Bush features elongated leaves and distinctive flowers that attract butterflies, diverging from the clover-like leaves and purple buds associated with Kudzu.
