Passiflora incarnata, the native Passionfruit, flowering beside the road at the bottom of Fern Valley

That's one incredible flower. Due to scrupulous weeding last winter they were a long time coming this year, but worth the wait. It's a fun plant to grow and hardy to USDA Zone 7 (maybe 6) but it can be a bit "enthusiastic". I don't care, but be aware. The fruit is edible, actually the seeds, but make sure they're ripe or it won't be fun.
