I love all the sedums in beds and in rock gardens and in walls,....
I cannot get sedums to grow in my planters .. Don't know if it is 1 . not enough water 2 too much water 3. not enough light 4. intense heat.
None are planted in direct sunlight so that should not be a problem but it was soooooo hot this summer maybe that did them in.
Then of course there are the rabbits grazing around and about
