Adding colour to grassy bank
I've got a steep grassy bank at one side of my my drive, which is covered in a hardy grass (not sure what, about 15-20cm high). I am really keen to get a bit of colour in there (love the idea of wild/meadow flowers). There is now way I can dig clear the area of all the grass, so I need something I can scatter/sow/plant, which will add colour and compete with the established hardy grass. Any ideas?
