Abundantly common but endangered in the Wild.
Catharanthus roseus is the plant I have been seeing since I was a kid and its everywhere in India. In marathi language (Maharashtra state, India) it is known as Sadafuli meaning Sada = Always fuli = blooming. This plant has escaped cultivation long back and now it is naturalized around houses and disturbed human influenced landscapes. This one is listed invasive in many countries as it produces small seeds that can be easily dispersed by ants, wind and water and can also be propagated vegetatively by cuttings.
This native to Madagaskar plant is now endangered in Wild due to loss of Habitat.
