Just one garden pot can hold an entire garden in miniature, a world of plants as visually compelling as a mixed bed and yet far easier to manage. That really is the beauty of containers. You don't need a big space to make a huge impact. What you do need of course are fantastic garden containers of different sizes, styles and colors.
There are so many different varieties to choose from in today's marketplace. Terracotta which is traditional, poly-resin for weight, concrete for durability and much more. When it comes to selecting the plants to pot then you need to make sure you get the ones best suited for the area you are going to place the potted container in.
When planting in the Southwest you can always go with the super durable cacti and succulents. A spiky aloe vera is lovely and grows rather large in most containers. For best drainage make sure the potting soil is formulated for cacti and not just ground dirt.
