  1. These flowers are beautiful and I appreciate knowing they are deadly if ingested, but I have hydrangeas and lily of the valley against my house and screened-in-porch and I’m wondering if just the fragrance of the lily of the valley is dangerous. It carries in the air so wouldn’t inhaling the fragrance be dangerous too? My husband has lung issues and I’m wondering if this could add to it?
