Birding trips are a great opportunity to do a little botanizing while out in the field. Today's photo was taken on a recent trip to Cool Springs, of Ashland County Park District, a diverse little habitat we used at both the OOS '08 Conference and the Ohio Dragonfly Conference in '07.
This is the native Celandine Poppy or Wood Poppy, Stylophorum diphyllum. It is often confused with the nefarious non-native, Celandine, Chelidonium majus. Both plants are members of the poppy family and have similar-looking flowers. The leaves are quite different to a botanist, and yet they could be easily confused by the average flora-phile. The quickest way to sort these confusing species is by examining the fruit. Wood poppy, Stylophorum has a hairy, oval fruit, much like you would expect on larger non-native (opium) poppies. While the Celandine, Chelidonium has an elongated, slender and smooth pod containing its seed. Clearly they are different beasts altogether.
The native Wood Poppy is the one you will want to plant. One more confusing celandine, the Lesser Celandine, Ranunculus ficaria is an alien plant you will want to avoid like the plague. If you attained both, the plague would be the easier to dispatch! :) Weedpicker
