OK, it's a weed. But I happen to think it's a very attractive weed, and I have been letting it grow, where it isn't in the way. Besides, birds love the berries. The plant can grow very large. These are about six feet tall. Look at those bright red stems.
The berries can be made into a dye, and the juice used as ink. One of the most interesting modern uses for the berries seems to be as a dye that coats a new kind of solar panel cell, greatly increasing its efficiency.
So, I'll let my poke grow, and enjoy it for what it is, a weed that can be useful, in many ways.
