Elephant Ear and Asparagus Fern make a great plant combination for a container garden-and they're both easy to grow! I know the asparagus fern is easy to grow inside, but need to look up other (Longwood- always worth the trip).
DIY - Homemade Gabion wall ie rocks encased in wire baskets and used as a retaining wall - creates a dramatic feature in a garden. No directions on link. Nice someone figured out how to landscape with river rock. I swear they grow!
