Hello,
I live in Nothern Brittany. I have a very nice garden, most of it surrounded by high stone walls. However, there is one spot which is proving difficult and I would like some advice as to what plant there. It is in a shaded corner, next to the house. Not much sun at all and can be very damp. I would like something which grows fairly tall and colourful. I could put up a trellis if needed but would prefer not to. Any suggestions ??
thank you.
