Wow! This was a surprise! This big, bright red flower with intense green accent petals stopped me in my tracks. It’s called Giant Red Paintbrush. It is definitely the Grandaddy of the Paintbrush family. Most of us are familiar with orange Indian Paintbrush, and to a lesser extent pinkesh-red Rosey Paintbrush and yellow-white Alpine Paintbrush. But the Giant Red is just as it is named — bigger than life.
