Here's my Leptotes bicolor - a wonderful little species. Still more flowers to open, but the first ones starting to go, so don't know if I'll get a better photo by waiting. Another one in the genus, less often seen, is Leptotes pohlitinocoi, just for variety. It grows under exactly the same conditions (filtered sun, outdoors on my patio, mounted so it dries out fast), and blooms about the same time.
