Hello my sister gave me a passion flower vine, about 10 or so with good roots. A few questions:

1) I want to plant them at a gate to a horse pasture which has zero shade. It appears this plant can tolerate that. Am I correct?

2) I did a search online and it appears that this plant is not poisonous/toxic to horses. Does anyone have any source that says otherwise?

3) My sister warned me of catepillars eating the leaves but from what I read online this is a natural thing. Will the catepillars actually kill the plant? I guess I could spray fungicide to prevent this if I have to.

Thanks in advance

Ruthie
