Sedums are one of the easiest to care for plants especially for sunny, shallow containers. The combination shown here, to me, is the perfect mix of bright colors. Now, the trick to growing these is good drainage and a good porous soil mix. Now the center red-tinged flapjack kalanchoe in the container is not reliablily cold hardy, but is very popular and treated as an annual. The goldmoss sedum (Sedum acre) and hen-and-chicken sedum overwinter well here. The planting mix that works well for sedums is a mix of a fertile soil with fine pea gravel and a product called chicken scratch, which you can get at a feed and seed store, in a 2:1:1 ratio. I rarely fertilize, and only water during very dry periods after the plants are established. Usually if your sedums are dying, you have either over watered or the plants have not established a good root system. A gravel ground cover is always a nice addition, too. These are truly carefree plants once they are established.
