Enjoyed the tour.
Walter's Gardens has a true blue plant called Gentiana True Blue 2" tubular flowers. There are a few varieties of gentian. Another one I found in a search was Bottle Gentian. It's quite unique looking with clusters of blooms resembling tulip buds.
Interesting! I am ALWAYS on the search for true blue flowers in a perennial. Most things they call blue are actually purple.. as you know. Those Chinese Forget Me Nots look so much like the blooms on Brunnera. Thank you for your comment. You always give me great suggestions 🥰❤️
Beautiful looking garden, its a pollinators dream.
