Sedum 'Autumn Joy'(Sedum spectabile 'Autumn Joy')'Autumn Joy' sedum rates as one of the best and easiest perennials for Maryland. Long-living and with a long season of bloom, it continues to shine when summer perennials peter out. Flowers form in midsummer, gradually turn pale pink and mature to a rusty red in fall. Then, sturdy flower heads dry and provide interest in the garden all winter. In spring, clear away old stalks for the attractive emerging growth. It grows best in full sun, but blooms in some shade. Tolerant of drought and soil type, it does not require fertilization. Easy-to-propagate terminal cuttings root in seven to 10 days.
