Foxglove is a magical looking plant that grows to 3 feet tall with drooping purple, pink or white flowers, sometimes dotted inside, along a central stalk. Its Latin name is Digitalis purpurea, which might sound familiar; leaves from the plant are a commercial source of the heart drug digitalis. If you eat any part of these plants in the wild, you too will likely have heart problems after a spell of nausea, vomiting, cramps, diarrhea and pain in the mouth. A doctor might administer charcoal to absorb the toxin or pump your stomach,
