looks somewhat like a hyacinth bean vine. Yep.

Zorba, is that a vine or a cutting from a shrub or something else? I doubt that it is Lablab purpurea (formerly Dolichos lablab) 'Hyacinth Bean Vine' due to the woody stem. The flowers\seed pods and lack of purple stems point to some other plant.

It's a shrub.
