This is called Jameson Weed...Named after Jamestown VA. It seems the colonist got "high" off this plant. It only blooms at night. It dies back in the cold, but come warm weather, it blooms again. And it spreads. This is the plant on one side of the driveway. We have 2 other plants that we never planted on the other side of the drive. It likes the rain. This is the most flowers we have ever had....at least 4+ every night on each plant.
