We are at 8,000’ in elevation in the southwest part of Colorado. This means any traditional gardening is out the door. Not too many plants or flowers work well up here. It seems if it is not here naturally it won’t grow.
However the Columbine, the state flower, does wonderfully. This year we found a new hybrid purple color at the local nursery. Being a perennial, the Columbine typically come back year after year. And the butterflies love them.
