I discovered a dwarf Penstemon digitalis this year. I've never seen one that is this small. It's barely a foot tall including the top of the blooms. All my other plants that came up from seeds are almost 3 feet tall. Have you ever seen one of this type of Penstemon that is that small? You can see part of one of the tall ones in the background. It's about 3 times as tall as this one is.
