Well it is almost spring and the real early weeds are sprouting and blooming. I have no idea what the yellow blooming weed is but it is all under many yards -under oaks - anyone know what this is? The weed in foreground is Star of Bethlehem - which comes from bulb and goes away in 30 to 45 days - pulling it up is the only remedy but the yellow one needs identification - help?

No the leafs and blooms are different and it does not match the profile -
as Clinquefoil blooms in late May through Aug and its Feb and wet.

Cinquefoil -

Potentilla simplex
Other Names: Five Fingers, Five-Finger Blossom, Five-finger grass, Sunkfield, Synkefoyle, Common Cinquefoil, Creeping Cinquefoil, Oldfield Cinquefoil

Habitat
Cinquefoil is a perennial herb native to Eastern and Central N. America from Nova Scotia to North Carolina, Alabama, Minnesota and Missouri. Found growing in dry open woods, prairie hillsides, roadsides, old fields and waste places. Cultivation: Cinquefoil is easily grown, prefers full sun but tolerating shade, in any moderately good well-drained soil. Sow seed early spring or autumn. The roots are long, slender rhizomes branched at the top from several crowns, from which arise the long-stalked leaves and solitary, yellow flowers that close up at night, and threadlike, creeping stems. The stem-runners root at intervals and often attain a length of 5 feet or more, spreading over a wide area. The name Five-leaf or Five Fingers refers to the leaves being divided into five leaflets. Each of these is about 1 1/2 inch long, with scattered hairs on the veins and margin. The margins of the leaflets serrated. In rich soils the leaflets are often six or seven. Flowers bloom in late May thru August. Harvest edible young shoots and leaves before flowers bloom. Gather entire plant, in bloom, dry for later herb use.

Coming up this early. It has to be something similar to the "star of Bethlehem". I suspect it has a bulb underneath--another escaped minor-bulb flower. Look through your flower catalogs or talk to a landscaper, or garden store that sells a lot of bulbs. Talk to the guy that buys the bulbs for the store.

Winter aconite is a possibility--its yellow.

These usually disappear after a couple mowings, before its even warm enough to spray--but why would you want to?

I say Ranunculus abortivus. It looks like some sort of buttercup.

Here is another pic. The butter cup seems to have different leaves and it does not appear to be bulb related.

Riggle - I think your are correct. After I posted the next pic I checked your suggestion and the leaves and profile match perfectly. I think is is for sure Winter aconite - http://en.wikipedia.org/wiki/Eranthis
