Autumn Joy Sedum and ???
I have a mass of Autumn Joy Sedum, and I made the mistake of planting dwarf delphinium in front of them - the foliage looks nice together (good contrast of color and texture), but the delphiniums are too tall, and they're not working with the sedum - I also realized (too late) that the delphiniums will be done blooming long before the sedum present their colors. Any thoughts about what I could replace the delphiniums with in front of the sedum?
