I've found a plant that is very small and has flowers that are basically
miniature potatoe flowers, white on outside and orange/yellow in middle

It porduces berries that look like miniature tomatoes (about the size of
rowan berries) but turn dark purple/black

The leaveas are not unlike potatoes/tomatoes but the plant grows not more
than about 6inches hight

Anyone know what it is and is it poisonous?
