This grower is sure of this plant identification.
I have about 12 different Trads, including Trad. (Callisia) navicularis; Trad. (Rhoeo) spathacea; Trad. purple heart variegata; Trad. (Cyanotis) somaliensis; dwarf trad. Pink Panther and a plant labelled Trad. Bright Star which I don’t think is actually a tradescantia, it’s about to flower on a flower stem unlike any tradescantia I’ve ever seen - will post a picture when it opens.
Tradescantia albiflora. This is a trailing perennial.
You will need to grow in full sun or partial-shade in fertile, moist to dry soil.
