Trailing plant for chimney pot.
I'm a newbie with a very small balcony. I have just been giving a chimney pot (which I will put a pot into) and am looking suggestions for a nice evergreen plant that will trail over the side. I'm in London with a west facing balcony.
Ideally something that's quite hardy and that will add a splash of colour during the summer?
Any suggestions would be very much appreciated!
