Garden pots and planters/troughs (GU21)

Hello, I'm looking for some pots/planters please. I'm looking for some 15cm (6") table top pots and some bigger planter pots (or troughs). i'd prefer coloured plastic or ceramic (I already have plain brown/black). They would be put to good use, I plan to make a display on the communal balcony at my Mum's care home.
