More than 68,000 Americans a year are poisoned by plants. Reactions can range from a skin rash or upset stomach to severe gastrointestinal symptoms or even death. Small children and pets are at highest risk. Common plants that can be harmful:
Oleander, datura, castor bean. Ask a garden center or landscaper for more information. Or check the Poisonous Plants Home Page of the University of Pennsylvania at http://cal.vet.upenn.edu/projects/poison/index.html
for pictures of these plants... and others.
