Gardeners' Notes:

Negative mountainviewer On Jun 30, 2014, mountainviewer from Fort Collins, CO wrote:

Terrible weed. It reseeds with a zillion tiny seeds so it's hard to get rid of it.

Negative mgpaquin On Sep 30, 2010, mgpaquin from Savannah, GA wrote:

I've got this stuff all through my beds every summer. I wear exam gloves when I pull it up. I don't find the sap irritates my skin, but it is sticky and relatively hard to wash off. The only possibly minimally positive thing I can say about it is that I've got so much of the stuff that no other weeds can germinate where it is. It acts like a ground cover...

Negative Malus2006 On Jun 4, 2008, Malus2006 from Coon Rapids, MN (Zone 4a) wrote:

loves dry areas but will grow even in partial shade - it won't grow in woodland shade - is tough to get rid of because of their low ground hugging ability - they even ooze saps like the other euphorbia species so those who are allegic need to be careful.

Amen to the above. The only thing that might be considered good, is that it pulls up easily by the roots.

Negative melody On Jun 13, 2004, melody from Benton, KY (Zone 7a) wrote:

A nuisance plant that germinates just about anywhere. It forms dense mats of foliage that discharge a milky, sticky sap that can be irritating to the skin.

There are clusters of tiny male and female flowers that lack petals and sepals, so they have no decorative value. They reseed in such abundance that they are difficult to eradicate.

Not attractive to insects and wildlife.
