Rio dipladenia with no flowers

Question

I purchased the Rio last year and it flowered a lot. I brought it inside over the winter and kept it alive. In March it started growing long vines at the top of the branches. I cut them off. I put it outside this year in the sun, and it has nice glossy foliage, but does not get flowers. It did get one more long vine that I cut off again. I also have some salvias in the pot, in case they make a difference. Why does it not get flowers? Thanks.
