i am not real sure it is dianthus....kinda soubds like snow on the mountain. that is a runner. It grows then lays down roots. 4-6 feet is a pretty tall ground cover. If you don't want to work that hard to get it out. Mow where you can and use round up, that way you are not spraying higher up and hitting you other plants. make a cone over the spray head so you are not accidently getting drift also. Or you can take newspaper layers and lay them as a weed block. onced laid get them wet and put a thin layer of mulch on them. nothing will grow through it. the first yr i used the paper and didn't have to weed for 3 yrs lol. one of my gardens is 12 x 39 bed

I so thank you and I know when a person enters and it looks beautiful the day seems to get started on the right foot. It's a tough bussiness for health care workers and I just try to stay upbeat even with plantings. Spotty was what I got from a Morris arboretum consultant, but not my style too. My boss did add he get lots of compliments so I know well enough as I'm not up there on the road often. I might spend a total of one day a year trying to keep it up. I do like the honks and when I know somebody and they stop I'm even more happy. I can't believe you liked the daylilies even though they where special ones. I'm slowly taking them out. Wanted to tie in with what Medford did down the road and I'm not likeing it. I have enjoyed that rusty potato vine and the blue salvia this year.

Pretty, delicate looking...so tough is stays bloomed and strong, grows over and beats everything else out! My error was to plant it among my other flowers, I pulled and yanked till I was blue in the face and it won! It even grew across the vicinity I planted like the wind blew seeds? Anyway it is best as a container plant or in a area to fill in with only this! It must be contained or a takeover is imminent! Linda H.

It's a type of Rumex, or dock. A very common weed and one with a deep taproot that must be removed completely to prevent the plant from regenerating. And it does seed freely so avoid letting the plant flower. It will respond to any broadleaf weed killer but that must be used carefully if the weed is intermixed with desirable plants.
