The flower below came from a three lobed leaf vine found at Lowes. The tag said Passiflora pfordtii but the picture on the tag had pale flower petals with darker sepals. The sticky paper tag on the container said purple passion vine. Does anyone know the exact name and if my butterflies (Zebra Longwings and Gulf Frits) will both like it?

Sorry the picture is fuzzy. The filaments (correct term?) are not really as blue as they look, more purplish.
