Flowers
Up faced deep crimson flowers borne on a raceme. The blooms form two separate cupped clusters that meet in the middle, like jaws. Squeeze the sides of the jaws, and the two clusters will separate, just like a mouth opening. Release the bloom and the jaws "snap" closed. Honey Bees are heavy enough and strong enough to open the flower.
