Solanum dulcamara - Bittersweet also known as Woody Nightshade. This relative of the deadly nightshade is also a poisonous plant, but far less so than its notorious cousin. The twigs, roots & bark are used in herbal medicine.
Deadly nightshade -- not for human consumption. It used to grow by my bus stop. I used to wait there at 6:30 am, staring at this shrub, thinking, "If I eat this, will I get out of school?" Such temptation.
