What would you plant with Phlomis russeliana?
I'm planning a bed along the front of my house (suburban semi), across the bay window. It will be just 60cm deep, and about 3-4m in length, in full sun, and I want to fill it with Phlomis russeliana - primarily for the autumn/winter stems. I was just wondering whether to put anything else with them, perhaps for a bit of spring interest, but I know they form quite a dense base and am not sure if anything else could compete in the same space. One end of the bed will move into a slightly larger area with (probably) a Pittosporum and other small shrubs, but the rest will be surrounded by hard landscaping. Any suggestions or experiences, or should I just stick to Phlomis on its own?
