Seen on Johns Island growing at edge of woods in dappled shade. Creek with marsh nearby. There were 3 plants where I was taking pictures- in a space about 6′ x 12′, so not growing very close together. Other plants scattered about in the same area also in dappled shade.
Plants are about 1.5- 2′ high, and maybe 3- 3.5′ wide. Flowers a bit larger than a quarter- I didn’t think to check if they were fragrant.
Photo taken on 5/17/14 about 7:30pm, as sun was setting, so white of flowers looks a bit glare-y.
I thought it might be Bloodroot, but the leaves and flowers don’t look quite like photos I found online.
this is called Bull nettle, Cnidoscolus stimulosus [the ‘C’ is silent]. The plant has sharp hairs on it that can sting, much like a bee or other nettles. It is a native perennial, and not uncommon in mostly sandy soils in the warmer states. It is interesting, but, as said, must be handled with care!
