Frog/fern garden bed

My shady bed has progressed quickly this spring! We used to call it my fern grotto, but with the pacific tree frogs enjoying it, John is calling it my frog garden.

Plantings:

• Astilbes in the back - two varieties. The white flowers bloom first, then the pink ones.
• Hosta 'Gold Standard' in middle (about six plants).
• A variety of ferns throughout, placed according to height. They include Autumn fern, Ostrich fern, Hart's-tongue fern, Tatting fern, Maidenhair fern, Japanese painted fern, Button fern, and Bird's nest fern.
• Impatiens 'Dazzler White' in front.
