White Dutch clover is the one that's generally recommended for lawns--it is, of course, white-flowered. :-) The only purple I can find on a search is purple prairie clover, which doesn't look right. It gets three feet tall, as opposed to Dutch clover's couple of inches. On the up side, if you like their clover, take the seed heads off of it when the flowers fade and scatter them on your lawn. You'll get purple clover. Seed heads are continuously produced on clover plants and may be gathered from mid-season onward. You'll only need about one ounce of seed per thousand square feet to fully establish the clover. Less will get it started and the stuff isn't real shy about seeding out all by itself!

This says not to use the Ortho on Centipede grass: http://www.ortho.com/smg/goprod/ortho-weed-b-gon-chickweed-clover-oxalis-killer/prod70214 The "clover" in the photo is actually a Lespedeza -- as opposed to Trifolium repens, the standard White or Dutch clover -- but when you get into the fine print on the label, Ortho's spray also kills Lespedezas. http://www.ortho.com/smg/products/ortho/weed_killers/weeds_in_lawn/pdf/WBGChickweedCloverOxalis_042009.pdf

Hi docmom, thanks for joining our discussion. ( : I have a weird situation here....no weeds except one type yet. Oddest thing I've ever seen. Anyway, so far so good. We will see what happens when it warms up...but the soil was bare for over 1 month and no growth when it was warm. weird and wonderful. So, going to try spot control for awhile. Then if things go like they have in my past gardens the mulch will be considered. I would also like to get my hands on some Bellium minutum Miniature Daisy seeds, but the only place that had them did not have free shipping, so cost too much. I have some creeping thyme seeds coming. Fun to hear from all, would love to see some pics of your projects! Blessings, Waterstar

This looks very much like chickweed: http://www.foragingtexas.com/2008/08/chickweed.htm If it is, it's kind of pretty and edible with delicate little white flowers. Mine seems to dry up mid-summer though, not to return til the next year. I need to find more chickweed recipes!
