A picture (nearly) a day for a year.
Sorry, but I don't know. Still, they're really pretty!
I hope you don't mind, but I asked my mom - knower of all things horticultural in So. Cal.She says if it's low to the ground, it may be Vinca. Or, if the flowers change color over the course of a few days (purple to lavender to white) it's Yesterday-Today-And-Tomorrow.Hope that helps. :)
