I have this perennial weed in my Zoysia grass. It has the little nodules on the roots. I do not let it go to seed, so it is spreading by the roots. I have not seen it in other yards – central AL, and it is not on any of the typical weed ID websites. What was a single weed in the grass several years ago, is now covering a large area. The flower in the picture is a day old and has closed. It normally is about the size and shape of a dandelion. Thanks for your help!

    You’re welcome! I had the “tuber” term from the US wildflower page. I didn’t know what it was called before. It took me a while to remember which is which for these plants terms: “bulb, rhizome, tuber, & corm”. Best wishes Kay! Laura

    Thank you! I believe this is correct. I was calling nodule incorrectly the little tuber/potato. The pre-bloom looks exactly like this. My roots look a little more delicate than the us wildflower pic, but I still believe this is it. I have hand pulled and pulled, but the “potato” cannot come through the zoysia roots and is left behind, making more next year. Sorry for the delayed response. I thought my upload failed and just resubmitted. I REALLY appreciate your post! I have done extensive search on this.

    The opened flower would help narrowing down its ID. I can’t see the “little nodule” clearly, it could be a tuber? Check out Potato Dandelion (Krigia dandelion) and see if you have a match. There are several methods with mowing and chemical treatments to control other Krigia species i.e. Krigia virginia (dwarf Dandelion), but I’m not able to find one for Potato Dandelion. In my humble opinion hand digging them out of the lawn is most effective for removal unwanted plants. Best wishes!
