This is a spreading, low, ground cover plant with holly-like leaves. The stems are tough and woody, upright, and do not branch. The leaves are alternate on the stems. Leaf color ranges from light to dark green. It's evergreen. Leaves are tough and a bit leathery. We've never seen any flower, fruit, or berry of any kind, just leaves. Each stem ranges from about 6" to 12" tall, occasionally to 18", rarely taller than that. It spreads by a tangle of underground runners/roots. It is somewhat aggressive and spreading. It is growing in shade under live oaks. It used to be in a St Augustine lawn, and happily survived regular and repeated mowing. That area is now garden and this "ground holly" is a pest. It's not inherently a bad plant, it is just not what we want where it's growing. It is proving VERY difficult to remove.
Manual weeding has little effect (breaking off stems, leaving the runners). Judicious and repeated applications of herbicide (Roundup) cause the leaves to die, but not the plant which continues to sprout vigorously. Current attempt is to spread a tarp over a section for the winter and see if it dies miserably in the darkness. Does anyone know what this plant is, or have any advice for eradicating it? We're thinking of this as the holly-version of Bermuda Grass.

I always thought these little guys were oak acorn seedlings...but if they have runners? I don't really know.... : /
I think what you have is Mahonia repens, a native type of ground cover.
Check this and see if it matches:

Ohh.. I have those, too! Thanks for asking, jessileigh!
Frostweed, Mahonia repens showed up in my searches and seemed a likely candidate -- it is similar, but the leaves are opposite on Mahonia. This plant has alternate leaves. Also Mahonia repens blooms. This plant has not bloomed. The roots are tough and tuberous. In my attempts to identify this beast I've used every keyword and keyword combo I can think of with no success.
Are there any oaks near these, or was there in the past? It just looks so much like a live oak motte!
Looks like live oak seedlings to me too. They can be tough to completely remove and just keep growing back. The only thing that works for me is to pull when its so wet I fear to work in the bed.
Yes, it's growing under live oaks. Seedlings do put down deep taproots fairly quickly making them difficult to remove. These have running roots with clusters of finer roots ending in bulbous nodes. Could these be runners off the oak roots? I've lived around live oaks all my life and not seen this before.
Live oaks often grow in what they call mottes. There may be several good size live oaks near each other or just one, but surrounded by these little live oak sprouts. All connected, part of the same plant, basically. There could be seedlings present, but mainly it's the tree/trees putting out these things from underground. In the wild, there is usually a grove of live oaks near to each other, all part of the motte. Many people keep the little ones mowed down or pruned back.
Linda - Bingo! I found several good articles that described it. Tom Spencer has a brief article on oak trees at Soul of the Garden that identifies the culprit. We have 3 distinct groups of oaks in our small woodland. The central one is where the motte is. We call it Four Oaks and I believe those to be Escarpment Live Oaks. About 30 feet away are two large oaks that do not have any of this growth surrounding them. These are definitely Coastal Live Oaks. Looks like I need to rework the garden plan in the affected area to allow for mowing.... We've been ruthlessly killing lawn and replacing it with gardens to eliminate that task! Ahh, the best laid plans, eh? Mystery solved. Thanks!!

Wow, a Texas weed that HASN'T made it into MY yard! I didn't think their could be one!
We planted some native plants, just a few, and I should have KNOWN (DUH) the reason they are native is their great ability to thrive here and create more babies!!!! So now I'm plucking natives out of grassy areas they weren't intended to be. Gardening is never done. =)
