Finally, I had success with a lupine! All the previous lupines died or never flowered. This one seems to have seeded itself around last year, so hopefully, I'll get a little group of them!
My Aruncus dioicus (Goatsbeard) finally flowered. I started it from seed three years ago. I have several plants, all interspersed along the back of this perennial bed. However, I think they would look better in clusters. They appear a little like Astilbe with their feathery blooms, and similarly like shade. Mine gets morning sun and afternoon shade. They are said to need moist soil and grow 4-6 feet tall. Currently, my plants are all 2 to 3 feet tall. At the right is Stachys byzantina (Lamb's ears) and the pink foreground flower is a dianthus.
