Hi Hannah, That link didn't work for me, could you try again? Are you in the northeast as well? I had a bunch more of it that I pulled out, but decided to leave one just in case it was something pretty. Until this weekend, it was all swamped by this year's Forget-me-nots, anyway.

Thanks for the suggestions! We don't like grasses in the yard, especially after helping our neighbor get rid of some really, really invasive grass that Urban Gardener planted in their yard this past year. We have a lot of shrubs in the area already, and are looking for something more low-lying (less than 2"-8" tall) to fill in. I've never really had a thing for mondo grasses, but we all have our loves :) Between the three spreaders/clumpers above (veronica, epimediums, partridgeberry) we should be able to work something out to cover at least 60-70% of the area in question, which would mean 60-70% less weeding, and something to keep the ferns company during the winter when many of the other things have died back. I don't mind spending $$, I'm totally fine with that, but ... I don't want something that is a tiny 6" clump at full size, else we will be seriously spending a thousand dollars buying 200+ plants to fill the bed. Are the three aforementioned species relatively safe to plant near perrenials that die back down to the ground every year and re-sprout, or will they choke those out? If it is not safe, what kind of spacing should I be trying to maintain between these and other plants? (i.e. would the average spread diameter + 6" buffer be adequate?) I am normally really wary of non-native species, seems like most of the common ones are too invasive for my liking, which is why I had to ask. Search was turning up a ton of results, but I couldn't seem to refine it enough to find meaty info. Thanks again for the advice! BTW - Epimedium warleyense and versicolor flowers both look amazing! (see pics halfway down page)

Jitsmith, as pertains to the Oenothera, check out the thread linked below--and I don't think you'll have any trouble at all deciding what to do with the stuff! Oh, yeah, the flowers are pretty---but too much of a good thing isn't pretty at all! I wasn't familiar with that particular Anemone, so I checked it out. I think your plan to stick it in a pot is a really excellent idea! :-) Zach, I hadn't even thought about snow-on-the-mountain, but that stuff is nasty, nasty, nasty! It's been a while since it's come up, but we've had folks around here in the past who were desperately seeking ways to get rid of it. If you have it in the grass I recommend Weed-B-Gon to at least knock it down some. Would probably take a long time to get rid of it all the way, but mowing it, rather than weakening it, will have the opposite effect. Mowing it will just promote new--and more--growth and it'll come raging back bigger and better than ever. I don't understand--and didn't when I was selling them either!--why these kinds of things are sold commercially, or at least why they're sold without a SERIOUS warning about what's gonna happen when you plant them in the ground!!! I used to try my best to warn people when I saw them picking out things like these. Houttuynia, Chameleon Plant, is another one, but you don't hear about that one as often as snow-on-the-mountain or Mexican Evening Primrose. I used to actively try to discourage people from buying Houttuynia! Pretty green/red/yellow/cream AGGRESSIVE leaves! The partly saving grace out here is the dry soil which slows it down some, but with moist/wet soil it takes over the world! Think Kudzu! There should be a Federally mandated warning on the pots for things like these! WARNING! This plant can be dangerous to the health of your yard--and to your blood pressure and your mental state!!!!!

Hmm. I used to go down by Hillsboro every year to look at wildflowers and collect seeds. Amazing how you always see something you haven't seen before! Good luck in collecting some. I just looked at the picture again and it definitely has me stumped. Why don't you send the pic to Mr. Smarty Pants at the Lady Bird wildflower center thingie? I bet they'll know what it is.
