Madagascar periwinkle

The name comes from its new flower, red, white, pink, and dark pink that blooms from beginning of summer to autumn one after another every single day. It contains alkaloids in whole grass and is used as an anticancer agent but its use by amateurs is dangerous because of its toxicity. The flower message is "build up".
