Massive blue rhinoceros horns arranged in a pot is how I would describe a container planted with Warrior Onion . Known as a bunching onion, it was an All American Selections winner back in 2016. That was the year my gardening friends in Tennessee introduced me to it. They were using it more as an ornamental than an edible, but who says you can't grow it as both. I think it is gorgeous as the thriller plant in a mixed container combined with some sort of silver-colored spiller plants. Warrior holds up longer than other onions and has a rich flavor.
