butter and eggs

A little past the white teepee, on the ground where not much grows due to old toxic chemicals, I saw these wildflowers hidden under the grass. The yellow wildflower is known as Butter and Eggs. In Newfoundland it is also known as Bread and Cheese. A beautiful yellow dye can be made from the flowers. Butter and eggs belongs to the snapdragon family.I wonder if it too "tames tendency to throw out critical barbs"?
