I have some chimney pots 4' high. I cemented in a base with drainage holes halfway down.
Wisehedgecrone. I would not put in a pot....why? Use them just like any other container. I would put gravel, grit, polystyrene etc in bottom few inches then use mpc for temporary plants or John innes for permanent ones.
I use mine for temporary/seasonal plantIngs. Pelargoniums for example. Fuschias. Grasses, Phormiums and Aeoniums look good too. I have convolvulous maritima in one chimney pot though. It survives here every year and cascades making a sheet of velvety purple/blue all summer long.
You dont say how wide your pots are but a clematis should grow well in them if you feed well. Bulbs? No problem.
