Note: These flowers are quite small compared to other passionflower species (only about 1-1.5 cm in diameter).

Unfortunately, a huge storm was on the way when I took this shot. It was rather dark out and the lightning had already started (so I was rushed to get some photos in before we left our land). Geotagged,Passiflora lutea,Summer,United States
