Answer: Sounds like a beautiful planting! What you describe with your sedum is probably Botrytis gray mold which attacks sedum leaves and flowers, causing blotches to form. Eventually, the leaves and flowers turn brown and die. To control, cut off and discard all diseased plant parts. Spray infected plants with a copper or sulfur based fungicide, making 2 applications 5 days apart. You may be able to avoid this problem by keeping water off the foliage. Hope this works for you!
