Thanks for the information. It actually says "absent" in NH, even though it is said to be found/endangered in a couple adjoining states. I really don't remember buying it, so I'm very thankful to a bird that might have bestowed this gift on me! I have a little colony in the bed so I'm very pleased to find out what it is, and do hope it expands.

I don't get bent out of shape concerning what people plant in residential gardens & I don't crusade the idea of going native to anyone who will listen. I figure if I make my own yard look good with natives, thats the best way to sell the idea but I'm not out to change the world. If someone asks, I'll answer. I'm not an average homeowner. I like the prairie and we removed the lawn and went that direction but then I keep in mind the perspective that I like gardening more than most who live around here. I'm not a sports fan which also places me in another minority, I'd rather be outside gardening during the game or when the Thunder plays. The toothpaste is out of the tube concerning our problem invasive species such as honeysuckle, Bradford Pear & privet. The popularity of the non-invasive plants you mentioned such as day lily, roses and hosta and several other popular landscape plants we could list is not the problem when you consider the amount of land covered in concrete and high maintenance lawns. I consider lawns to be a much more serious concern than whether people prefer native as opposed to conventional garden plants. Water waste is one of my biggest bug-a-boo's with sprinkler systems becoming very common, widespread chemical use on lawns that runs down the street into streams and air pollution. I find myself doing the math of what I see going on here and know is going on elsewhere. There are strict restrictions on ranchers and farmers, officials regularly check to see if they are in compliance while homeowners are free to spray their lawns with abandon. This makes no sense. I don't like seeing the city expand and watching builders scrape off the native prairie and then replace it with bermuda lawn grass and formal landscaping along with regular mowing, spraying and sprinkler systems. Fire suppression is a bigger cause of problems than introduced plants where I live. Eastern Red Cedar is out of control and is taking over thousands of acres of prairie at alarming rates inevitably creating deciduous forests of both native and non-native woody plants. In my opinion, it makes no difference whether they are native trees & underbrush or not at this point. Why should it? That land cannot be restored back to prairie, habitat is lost forever and it seems there is no stopping this aggressive transformation, no end in sight. When its dry, these infested places turn into infernos that explode. After the fire is finally out, the trees are what come back, not the grasses. Its a problem of balance and funds. Fracking is a major concern. We have earthquakes here all the time now, I heard we have more than California or anywhere else in the world right now. I also worry about the fact that we are depleting the aquifer faster than it can replenish itself with large scale farm irrigation. We have a vote coming up concerning something called 'Right to Farm'. Its about halting regulations on farming practices. I'm not sure what its all about since I haven't had time to look into it but it sounds ominous. Has anyone heard of this?

I've got a similar tricky spot. Waldsteinia is one of the few thing that flourishes there for me. I'm surprised that two Sanguinaria I planted there about three years ago have formed a little colony now. Other stuff I've tried seems to hang on but not thrive.

Thanks for replying Floral, but, if I knew which kind by name, I could likely find it. I just know it's a North American native, it's native in Pennsylvania, where I live, and I had actually purchased it before, and planted it, but, I think I planted it too deep or something, but, the roots were so short, but, anyways, it isn't likely to come back up. But, REALLY, it's too early to say for sure, but, I want to get more plants anyway. It's a shade loving thick bladed Pa native Carex plant. I've seen it growing wild in the mountains not really far from me, after I first saw it I ordered and planted it, which is the planting I reffered to above where I may have planted it too deep. So, you may not know it as far as it growing in the UK, but, hey, it may for all I know, but, I do kinda doubt that it does, at least naturally, but, I bet if introduced it would love moist woodland soil in the UK, unless it needs a different PH soil.
