I've tried to grow Verbena homestead purple. Could not get it to over winter.
I grow Penstemon Red Riding Hood. It is three years old. It is red. They didn't have the different color Riding Hoods back then. Mine is a trooper! Blooms ALL summer long and into the fall. Still blooming now even after lots of hard frosts. Also the plant gets large for me and I divide it for other areas of my garden. Early this fall I bought two of the new colors on closeout at Lowe's or Home Depot. Can't wait to see them in spring
