I have one too, I think it came from the Swap? It isn't doing anything for me either. I also bought a variegated Sky Blue Vine. It isn't doing much either but I will dig it up and hopefully over winter it for next year. It is very pretty I wasn't really sure it would bloom for me this year. I had beautiful gloriosa lilies thanks to Sally. My Hyacinth Bean is going great guns hopefully I will have seeds for next year. The hardy passion vine and Blushing Susie vine are doing great. I planted the Mandevilla and Sky Blue Vine on the front of the Gazebo where they would be well seen but the Big Portadoras block them so they really aren't very visible and I wonder if the SBV would have grown better in a different location maybe it isn't getting enough light with the Portadora in front of it. I need more trellises.
