Can anyone help me with this? What is this?

I think it is called snow on the mountain. I have a patch of it in my garden bed. Next year I am moving it to the lower end of the garden. It does spread quite fast. Even if you till the garden under the roots may still be there come up again. Just pull them out and keep yanking them when you see them appear. Eventually you will have it eliminated.

It is great to grow on slopes where it is very hard to mow. But like any other plants it needs light to grow so if you want to kill it then make a blanket of mulch thick enough to entirely cover the plants so that they will die from lack of light.

Yes, it is snow on the mountain. You can remove it with roots and plant in other place. I like it on places where I don't want to cut my grass over and over...so I have ground cover...especially in my front yard.... It is hard to eliminate. The only way to eliminate it is remove all with roots.

I found what it is, but can't find how to kill it. I have it in my garden and just keep pulling it out. http://www.aboutvines.com/vinca_vine.shtml Vinca Vine The vinca vine is a trailing vine that grows green and white leaves. A vinca vine is very fast growing. Vinca vines bloom with delicate violet trumpet like flowers. This vine will not climb surfaces, but can be strung over wires or other such mediums, and makes a wonderful ground cover. Vinca vines are most hardy in zones 5 to 11, and should be treated like an annual vine in colder climates. The vinca vine can grow in full sunlight to shade and should be watered regularly, with good drainage, to keep the soil moist. Too much water can easily kill a vinca vine. The vinca vine, often called a periwinkle flower, is used often as a grass substitute in lawn areas. The plant will only grow to three to six inches off the ground, but the trailing stems of the vinca vine can spread up to eighteen inches. One thing to note about the vinca vine, however, is that it is extremely invasive. This means that the vine will easily spread throughout the garden quickly and can overwhelm other plants. Great care needs to be taken to ensure that the vinca vine does not take over the entire garden.

Yes it is best known as snow on the mountain. You can pulle them out and transplant to an area to control them better. They are actually a lovely plant for ground cover. Heres what I did with mine. They are very evasive and spread anywhere and every where like creeping charlie. If you don't want them they are like a weed that keeps coming back when you pull them.
