This photo was eye-catching. First I thought it was a princess vine, but Al, my FB friend identified this as Wandering Jew, but mentioned it was called a buyo-buyo.
On second viewing, Al think it is still a buyo but crossed bred, probably with a blackpepper vine.
For more details on "Piper abbreviatum Opiz" or buyo-buyo: Stuart Exchange.
