What are you thinking about puting in your yard? We can get a vast number of plant that are native to the area and several that have climatized themselves to our hot dry environment.
Trees and shrubs can be broken into several categories and container sizes. Container size is determined by the gallons of soil the container will hold. Sizes range from a 24 inch box to a 25 gallon bucket and continually become smaller down to the size of a 1 gallon bucket. Some special plants like bedding plants come in smaller containers.
