What Plant is This?
There is a plant in my yard that is annual, comes up in the spring, does not flower, and produces dark purple berries about 1 cm in diameter every summer. It does not look like a shrub it grows on stalks that are also a purplish color and grow to be about 7 ft tall with large green flat, smooth leaves. This is only the 3rd season I have seen them growing in this spot, I did not plant them and they seem to spread and grow taller every year. I have looked all over and have not seen them growing anywhere around, what type of plant is this?
