I'm completely new to gardening so will probably be on here quite a lot this year asking questions! I've got a north facing front garden, and have a space for a hanging basket by my front door. It gets no sun at all and it always seems quite damp out there. What kind of plants could I put in a basket there. All I know is ferns, but I was hoping for something trailing and maybe colourful to fill out the space as well. Any suggestions?
