This is something new (to me) this year. I found this at a local nursery and thought it looked a lot like a Delphinium. But it is actually a snapdragon. Angelonia angustifolia 'AngelFace Blue'/ Summer Snapdragon.
I've been moving it around, first had it sheltered, but it wants sun. The Proven Winners tag says it's easy to grow and is drought tolerant and deer resistant. Would have liked to have tried it at my former home, aka deer central.
