One corner of our patio has a house wall on both sides, meaning it gets no sunlight on it at all . It has a ledge, about 6 inches deep and 6 foot long, that is currently empty and just looks dark and damp. I'd love to have a row of small plant pots with something colourful along there to make it more slightly. Something like bright red pelargoniums, except I'm sure they won't like the shade. Can you suggest anything bright and cheerful? The rest of the garden is still work in progress, but I'm aiming for a cottage garden feel
Thank you
