Earlier this week I happened upon several patches of Wineberry plants (Rubus phoenicolasius) growing in an especially weedy strip of land between parking lot and highway in Hunt Valley, MD. It is easy to recognize this invader by the long, gland-tipped red hairs covering the stems. According to this fact sheet from the Plant Conservation Alliance, Wineberry was introduced introduced to the U.S. in the late 1800s for use in breeding new types of Rubus berries (raspberries, blackberries and the like). As with most thorny plants with juicy, edible fruit, its dispersal into natural areas was both inevitable (birds say "Yum!") and unwelcome (humans say "Ouch!").
Because you are probably wondering, yes, there is a recipe for wineberry wine.
