Sedum makes an ideal plant in containers and troughs due to its ability to resist drought and heat, in fact preferring those conditions.
Growing Sedum in sandy soil, among gravel or rocks or in fast draining containers is its favorite situation.
To trail over the edge, choose those that tend to spread, and plant more upright types in the center of a large pot or planter.
Some of my favorite planters are hypertufa pinch pots - the hardy succulents that I plant in them love the rough texture of the concrete and peat moss mixture.
The textures of all these combine to make a tapestry or patchwork quilt effect.
