I keep thinking that I have way too many pots; but found a good deal at Old Time Pottery - huge clay pots and some reall nice ceramic ones. I picked out a very large ceramic pot, with a wide top -- this one's going to be a water garden.

I like the clay pots for the cacti & succulents but they dry out too fast for the other plants.

But you need to keep the plants in their plastic pots and put those inside the clay pots !
