is zinnia or passion flower poisonous?

[jason g.]

I've been looking about several plants I'm planting in my outdoor enclosure so far all are good accept sunflower, and I can't find anything about the passion flower. I could of swore I read zinnia was OK but now I can't find it. Sorry I'm looking the best I can but I can't find these. I did find 10 different plants that were OK.

Passion flower I've heard both ways. May be better to play it safe until it's known for sure
