Trying to Find Plant Name

Question

We were at a garden fest yesterday in Melbourne, Florida. There was a tent set up selling mostly “butterfly” attracting plants. There were some viney looking plants on trellises that were a bit more pricey that we could pay. They had light purple or maybe blueish tiny flowers. We both bought the smaller versions with no flowers and would love to know name so we know where to plant, type of care, soil etc.

Answer 1

I am leaning towards Clerodendrum ugandense or Butterfly Pea Vine. Take a look at those two and let me know if either one of those may be it. If not, I will keep looking.
