I like dwarf mondo grass - Ophiopogon japonicus is the name. It is not monkey grass (Liriope). When I used it, I bought it at HD and then split the clumps into two plants to make it go further. I saw an article in Southern Living about planting it in a grid pattern - worked out nice.

One plant I would definitely not recommend is vinca major (nor would I recommend vinca minor, as it is almost as bad). From personal experience, these have both become invasive in our yard. At first they looked lovely sitting all neat in their beds. Then I had difficulty keeping them from growing up trees. When they did they would bore their roots through and into the tree's bark. We have a large yard. I became sick for a couple of years (this was after they started to become difficult) and couldn't get out to do much yard work, and by that time they grew up most trees that are in the yard and weakened and ultimately led to the demise of many of our lovely trees. Also, causing a hefty tree removal bill. It has become a landscaping nightmare to rid these vines from our yard. They are tough and hard to pull by hand. Also, being under other trees and shrubs and near other plants, chemicals are also difficult to use without killing others.

I have used Ardisia japonica (Marlberry) and some of it's variegated cultivars on a landscape project on St. Simons Is. and it does quite well in sand under the Live Oak trees. There was a thin layer of leaf compost present, however. Rb Here is a link that might be useful: Ardisia japonica

Zack, I didn't post it because I hole heartedly agree with it. Again the "truth" might lie somewhere in the middle. I read "at" issues from many sides. The rancher manages 35,000 acres and I have found that controlling 17 acres is about making choices that have me riding a world where I do not control everything that comes my way. I can only imagine what the uncontrollable issues that he surfs. He has documented yellow star thistle patch and has found that it usually goes away after a decade if left alone. I found that surprising, even confusing. KR bluestem is a species that many people love to hate here in Texas. Yet I do see the butterflies going for their inflourescens during migration. I also see the native bluestem multiplying in the front field amongst them. It appears that on dry summers, it does not make much of an appearance or a very late one, giving the natives a chance to compete.. I know that I do not have the financial nor energy resources to dig them all out. Fire was said to control it but now they have back tracked on it. I am trying to keep it out of the valley where I have a delightful native community of Muhlenbergia s of different sorts. Nor do I want to poison everything out only to have the wind bring more to the empty soil. I was interested in the Monsanto angle of the board of directors mentioned in this Book review .It is more of the same thinking and written by David Theodoreopolis of J L Hudson Seedman fame, so he does have skin in the game and makes money selling possible invasive exotics AND natives. He is a controversial figure. I do find what he says about the fear of change valid and where do we stop the ecological clock since it is a forever changing thing. I just wish it would not change so fast. I have also and aesthetic concern about loosing some ground hugging spring ephemerals to the always land hungry bastard cabbage. Like I said, I do not agree with everything. that he says. I do find that much of the language used by some do or die native guys to be wishy washy as to what is a native and what is not. At the land conservationist meeting here in texas, there are 2 camps about the invasive grass KR Bluestem. 1 states it is a bad bad monoculture forming invasive that is good for nothing and and the other camp says it is a good land stabilizer and good at getting water to penetrate down to the water table. Another is that burr clover that was used as green manure and escaped. It grows in patches and I am tired of digging it up and it will improve my soil. My soil needs soil improvement desperately since invasively farmed cows have been overgrazing it for decades before I got here. Maybe it will disappear as it incorporates nitrogen into the soil.The soil washed away. I won't plant uncontrollable non natives because of the guilt if they escape issue. I prefer natives but I am a practical minded human when it comes to picking battles of whom I eradicate, where and how. The info keeps changing. I do not want to cause harm. But I do not know what is harm sometimes. My thinking is changeable about this subject. There is a lot on his site that is interesting. He uses Holistic land management ideas. He brings up that the removal of all herd animals off the grasslands and high deserts is harmful. .Balancing them is essential but these lands always had herd animals of sorts and many of the natural ones are gone and the niche is filled by cows. There is a connection between the desert tortoise populations and the herding of cows now. Desert tortoise populations have gone down where the removal of all cows have happened. Go figure. The politics of Rancher removal by the BLM is very troubling. Then they seem to give the rights of the land off to Uranium miners. Yes there is uranium under the Hammond's land. OOPS I didn't mean to open that can of worms.
