I'm currently rethinking my large flower bed, and I'm always on the lookout for inspiration. This post on container gardens from the Terrain Bulletin has some great ideas. I especially like this combo since I want to incorporate some ornamental grasses, and cone flower and hyssop are two mainstays of my garden. The structure the grass provides will help support the cone flower and hyssop, two floppers.
North Creek Nurseries will do:
Another garden renovation/expansion will have to wait until fall.
