Hi all , I have been given a large pot for my patio. What can you reccomend to plant in it. It is 18" tall and on the bottom is stamped 75 litres which I assume is what it holds . It is black and made from something that resembles terracotta but won't be damaged by frost. My patio faces South East so it is full sun until 4pm. I used to have a lot of pots but started to cut them down because of the watering but I have been given this pot by a friend who is a frequent visitor so I can't just stick it somewhere and forget it. What shall i put in it, Help please.
