Lantana. Introduced in India for its flowers, this species is invasive and large tracts of barren/ forested/opens have been over-run by Lantana. The flowers come in a variety of colors. It is a host to a variety of insects - especially Butterflies and birds love its berries.
Love this flower and its different color variants.
Pinks and yellow- this is the commonest wild one.
Mauve... quite a looker.
White... dialed in a bit of -EV to get this right.
