Passion flower

This is a new thing for me. It's Passiflora incarnata, called Maypop because its habit is to die to the ground in the winter and then pop up all over the place in May. I planted it last year and it performed as promised. It's growing up through the branches of a Carolina silverbell (Halesia tetraptera). Here are the first flowers I've seen. It is caterpillar food for Zebra Longwing and Variegated and Gulf Frittilary butterfly larvae.
