Sounds like maybe you scored a Sollya heterophylla or Australian Bluebell Creeper. A semi-vining evergreen shrub with blue summer flowers, so a trellis for support may be advised. And I'm not sure of the hardiness - most sources list zones 10-11 or a minimum winter temp of 25F.

other plants that go by Australian bluebell are in the Wahlenbergia genus,such as W. stricta, gloriosa, gracilis etc.
they are in the campanula family.
Some in this genus are annuals and some are perennials with varying hardiness zones.

You see it offered locally because Sollya may grow up here for some years but eventually freezes.

Sunset WESTERN GARDEN BOOK rates it Sunset 8. Also says it's sensitive to poor drainage.
