Jack, Sedum is good to have in the fall when there isn't much else out there. A lot of pollinators will be working sedum.
I know I have said this before, but I will repeat myself. In the spring I take cuttings from sedum to multiply or give away. When they reach about 12 inches tall, in the spring, cut them down by 1/2. I dip the ends in rooting hormone. It probably isn't a necessity, but I have rooting hormone on hand. Place a group of the cuttings in a new pot filled with potting soil. I will put enough cuttings in the new pot to make it look full. I make holes with my finger and stick the cuttings in. Water and place in a protected place from wind and strong sun. In a few weeks the pot will be filled with roots so that you can transplant into the ground. You can't hardly kill a sedum. Cutting them back prevents them from flopping over in the late summer. If allowed, they will splay out from the center landing on anything in it's path. Trimming back in the spring keeps the plant in a small shrub form.
