Plants have great P.R. Sure, they seem to be innocent and harmless. In fact, many of our photosynthetic comrades—perhaps the very houseplants in your apartment—are heartless killers. Venus flytraps, for example, are cruel enough to outrage the most jaded PETA activist, enticing insects with the promise of sweet nectar, then murdering them in cold blood. In “The Provocative Perfumes and Chemical Espionage of Plants,” chemical ecologist Joseph Pratt discusses how the flowers and trees outwit the birds and bees. At 6 p.m. at the Museum of Natural History’s Baird Auditorium, 10th & Constitution Ave. NW. $12. For reservations call (202) 357-3030. (David Plotz)
