There is a gap of stony, sandy soil, about 6 inches wide in places, between my front garden wall and the pavement. I've just spent an hour pulling up huge weeds (some 1-2ft tall) from it. The council don't appear to do any maintenance of this area, possibly because there's no grass verge to cut etc.
What would happen if I scattered seeds or even actually planted some compact, low-growing flowers there (thinking saxifrage or similar)? It's a west-facing wall so gets plenty of sun. I'm not thinking of anything that would spill over onto the pavement and cause a hazard, obvs.
Is this a mad idea?
