I scattered seeds throughout my backyard. Few of this plant which I don't know what it is. Please advise where and how to search for this plant ID. Thank.
A Nightshade for sure. Looks awfully like Atropa belladonna, Deadly Nightshade, but I'm not completely positive of that. Bittersweet Nightshade, Solanum dulcamara, looks very similar, but grows as a vine. Both are toxic plants, with Deadly Nightshade being more so. The USDA map link below indicates that A. belladonna and S. dulcamara are naturalized in your area. http://plants.usda.gov/java/profile?symbol=ATBE http://plants.usda.gov/java/profile?symbol=SODU The source below recommends the use of gloves to remove Bittersweet Nightshade http://www.illinoiswildflowers.info/weeds/plants/bittersweet.htm It would be wise to use gloves for removing Atropa belladonna too.
