Other info . - All parts of this weedy species are toxic when mature but the young shoots and leaves can be eaten when cooked. Why take the chance when there is a grocery store on every corner? The "ink" from the berries will stain almost anything it touches.
This is an easy species to ID in the field because of its big, alternate leaves, reddish stems, long inflorescences, and purple berries.
