A friend gave me this plant and told me it was a purple wandering jew. However, this plant doesn't wander. All of the pictures I look at, shows the wandering jew mostly on the ground or in a hanging basket, but my plant's stems go straight up. It's almost a 1.5 ft high and is still going up. Attached are pictures of the flower it produces and a smaller plant that was grown from the original. Is there another plant similar to the wandering jew that grows up?
