Posted this in the indigenous plants forum, but wondering if anyone in my area can positively ID it.....? Found this vine today climbing up my porch, and was thrilled to see the typical "passion" type flowers. From perusing PlantFIles, it looks like Passiflora lutea, but not sure. Wondering if its wild, as it seems unlikely it was planted at that spot. Its probably been there awhile, as I've pulling up wild grapevine at that location and probably just kept pulling it up, too.
