Genus Lantana

I am confused to say whether this is a wildflower or an ornamental flower, in my area we can easily find this flower almost anywhere whether in the forest, in the plantation, or in front of the house, many people choose to cultivate this flower because it is very easy to care for and minimal cost, and to get it is also very easy. I myself do not know the name of this flower but this flower has several colors such as orange red, purple and pink, I do not know the cause of the change in the color of these flowers but what is certain is that this flower is a very unique flower.

However, we must remain careful because this flower has a tree covered with fine thorns, the thorns can not cause serious injuries but are still uncomfortable. I myself managed to find this flower in my cocoa plantation, and there are lots of these flowers growing in almost every corner of the garden.
Okay friends, here is a picture of this wildflower
