These are flowers and fruits of Jerusalem cherry (Solanum pseudocapsicum). The flowers resemble those of black nightshade (although the fruits do not). The Jerusalem cherry is called "Tama sango" in Japanese, meaning "ball coral" after the fruit shape and it being as beautiful as coral. The fruit is inedible, i.e., poisonous as other plants in the Solanum family, but pleases your eyes with the color change until December.
