Purple Heart

Oh..its a herb of Commelinaceae family..like Murdannia..!!

Thanks for the help, guys! The leaves were purple and the petals tapered slightly like the Tradescantia so I think that's probably it.

I can't see the whole plant, but if it's kind of a trailing groundcover with dark purple leaves try looking up Purple Heart, Tradescantia pallida, and see if that's your plant.
