I knew goji berries were a vibrant red but little did I know their flowers were a brilliant purple. Perhaps they were glad that I got the trellis stained and tied in place for them. Although I’ll probably take it down for this winter and cover the goji bush. In the end decided to go with a semi-transparent coat, gave it a nice gold sheen but without the brown tint that we have been using on the chicken coop and planting boxes.
