We have them both plants here in Ohio as well and I love them It was only recently that I realized that Creeping Jenny was actually introduced here. (Warning: Complete tangent ahead) I went to a bonsai show and they were selling Lysimachia japonica and it led me to look up what other species of Lysimachia are out there. It was then that I found out that Creeping Jenny is not native to North America. Who knew?!? I also learned of another plant to search for while collecting native plants: Lysimachia thyrsifloraGood eyes, pweifan! Yes it is Forget-Me-Nots mixed with some Creeping Jenny that I pulled from the edge of the lakeshore. Both grow naturally (okay, apparently they are invasive, but they have been in NY "forever" now) thoughout my yard at the lake - around here the F-M-N flower shades range from blue to pink, but I never see the white variety that sometimes is sold. Some would call it a weed, but I love it. I kept the top of the soil about 2 inches above the waterline and it really took off. I plan to add some more of it next spring and it will probably spread out of the pond as well as it seeds itself. Next year I will need to get some good pics of it while it is still flowering - it was covered.
