I was looking for something to draw in my nature journal while camping this weekend and noticed some poison ivy growing under a box elder at our campsite. The leaves are remarkably similar in shape, but I've never had trouble telling the difference. I learned to identify poison ivy as a kid and have always been able to spot it in all its forms, even without leaves. Still, it's tricky to describe the difference between poison ivy and box elder to someone by leaves alone. I thought drawing them might help me notice some differences. Can you tell which is poison ivy and which is box elder? I'll post the answer in a few days.
