I have tried other ways to present my plants and some have advantages over others. This is the rack that I prefer to use for now. It is made from angle iron and flat metal, it is treated and painted to hopefully extend its lifetime in this unforgiving environment.
I have also tried some fiberglass pedestals for individual pots. I painted this and it doesn’t look bad it is just not very large and if the plant is too big, it becomes top-heavy.
