Wild Indigo \ Baptisia
True blue, June flowers form on this, one of the longest lived perennials known. It even has delicious edible flowers (yes, we where surprised too!). Just strip flowers from stalks and pop into your mouth, green cap and all, for a fresh pea fix. After a short bloom, the unique foliage contrasts with neighbors all summer and then it turns purple after a freeze! Place it next to yellow conifers for excellent winter color. It's a nitrogen fixing legume to boot!
