If a container is large, 60cms tall, you can grow quite a lot. I have clematis and some of the smaller David Austin climbing roses in them, but they do need regular feeding and watering.
A friend of mine has galvanised cattle troughs as planters, some bought on EBay, some new from farm suppliers. There is a plug hole but he drilled more for drainage. They look quite good in his garden.
I have a scented clematis in a pot, Betty Corning, she flowers quite a long time.
Most of my pots are terracotta (mind they are frost proof) and resin that looks like terracotta or lead, also some fibre glass mixture ones. The only wooden one that I had only lasted a few years.
