Had a gap in one if my borders, noticed a perennial coming through that I'd forgotten and was pleased it would fill the space lovely. Went on hols, came home dying to see how it looked and the slugs have completely eaten it. Any recommendations for a smallish summer flowering filler that the slugs don't like? Not fuschias because I have 2 in that border. I'm probably too late to see anything come to fruition this year but planning for next year. Any ideas?
