BRIEF: Can Red Tip plants cause cancer?

I'm purchasing a house that has several (25 - 30) large Red Tip plants in the back yard. I have a friend that tells me she's heard that they cause cancer. Do you know anything about this ? Or can you check around and get back to me?


Cause cancer how? By looking at them? Smelling them? If by Red Tip you mean Photinia fraseri, this hybrid bush is used all over as a hedge. The worst thing that I have heard about it is that the smell of the flowers is pretty obnoxious, so you will need some pruning shears. Since it is not a food plant or herbal medicine, I am not sure if we know the effects of eating the stuff. I will check other sources...
