Moon phase: Waxing gibbous Weather: Rainy One of my favorite plants is bloodroot (Sanguinaria canadensis), though I can never seem to catch it to take a picture when it's flowering. Bloodroot is native to eastern North America, but it's rare and it's listed as endangered in some places. There are a few in select places in Rock Creek Park, which is where I found this one. Native Americans in this area used its reddish/orangish juice to make body paint.
