Looks like Viola (violets). While I dig them out of my beds, I leave them in the lawn - the flowers are cheerful in the spring.

They are very difficult to get rid of chemically, so your best best is to a) do a lot of digging and b) cultivate a healthy, thick lawn. And enjoy the flowers. :-)

Thank you much for the info.

Though I like the Idea of flowers. Just not in my yard. Maybe I will put some in my front yard garden that doesnt have anything in it and the rest will have to go.

On to research! Thank you once again,

Many people post on Garden Web about trying to eradicate violets from their flower beds. I'd think carefully about whether they would fit into your vision for your garden. How much of a controller are you in your gardening?

Violets propagate via rhizomes ( if I recall correctly) a tough woody type root basically, a standard weed killer like 2,4-D will knock the leaves back but won't control them. They are pretty but are problematic when growing turfgrass as they tend to completely take over.

I have had very good results using a product called Crossbow in a gallon tank sprayer for spot treatment, it is also effective for other weeds. Violets have a waxy coating on their leaves, a small amount of dish soap (the liquid) mixed allows the product to stick to the leaves, increasing effectiveness. Weedkillers are best applied when weeds are actively growing, after a rainstorm or irrigation. High temperatures and drouth put the lawn into stress, weeds hibernate, therefore, weedkiller applications under these conditions may cause temporary dieback of the grass plant, while leaving the weed almost unaffected. Violet control is not a "one and done" kind of deal, it will take more than one season. With good cultural practices over time a thick healthy turf will better resist weed infestation and require very few chemical treatments.

You're right, of course.

The woody rhizomes make them difficult to control, is what I should have said. And, there's this -

Cultural control: Cultural practices such as proper mowing, fertilization, and irrigation can be manipulated to control some weed species but these practices have little impact on wild violet populations in lawns. Wild violet can be decreased by more frequent mowing but not by fertilization. It is unknown how irrigation, drainage, and soil compaction influence wild violet populations. As such, turf managers rely on herbicides to control wild violet.

I appreciate all the input, i used this

The leaves on the Violets have started to whither a little. I did this spray about a week ago. Now I am gonna mow since the damage has been done and spray it again with this and hopes that it will take care of the problem...then I plan to seed my lawn after about 3 or 4 days ( the bottle says 2) and then let my lawn grow grow grow and then mow it as long as I can and fertilize...I think this is my best course of action. After this second spray though, I have to wait till next year to do it again (per bottle)

Unfortunately that particular product will not provide any effective control. As mentioned some weed killers will knock the leaves back temporarily, but the tough woody rhizomes will send new growth.

Products containing Triclopyr are shown to be effective. I mentioned Crossbow as an example. It is much less expensive as it is a concentrate.

Weed B Gon products containing Triclopyr should work for you. It is marketed for Chickweed, Oxalis, and Clover.

lol sorry i just grabbed a purple label weed-b-gon off of google. I did get the one that you just posted.

just changed the image above to the right product.
