A while back I was asked if I had any examples of how to use succulents in a landscape. It can be a bit tricky to only use succulents because people tend to use the same textures and colors. The trick is to mix it up, using different height and shapes, as well as different textures and colors. For example, using a large Agave Attenuata or Barrel Cactus with Senecio Mandraliscae planted around it would be beautiful.
Below, I have collected a couple of examples.
A great mix here — Kalanchoes, Senecio, Agaves, Barrel Cactus, Kangaroo Paws, and Sago Palms
They mixed shape, texture and color beautifully! (Barrel Cactus, Senecio & Torch Aloe)
The color contrast here between the blue of the Echeveria and the green of the Barrel and Opuntia is stunning.
Succulents and Cactus are perfect plants and when mixed well they can produce a gorgeous garden with little maintenance.
Another great resource is Jammie Friday’s board on Pinterest called, Arid Garden.

This is so awesome! What a fantastic design. Did it start small and wimpy? How old is this garden, I wonder? Can you tell I’m not one with much patience? It might be worth cultivating, though, it get that effect. Thanks for posting!
Hi Diana, I am not sure when the garden started but by looking at it I think it has been around for a while. If you don’t have tons of patience (like me) I would say buy some larger succulents/cacti so you have some immediate satisfaction and then add some smaller ones as well. Good Luck!
