Another favourite combination in my garden - Alchemilla mollis and Geranium 'Brookside'. Both are hardy, long flowering and have decorative leaves. They are also easy to look after and don't get any pests or diseases.
I have picked some Alchemilla to dry for winter. I have done this successfully in the past but I have almost left it too late as some of it is starting to go over. I have tied it with some fine wire which I will tighten as it dries. I have it in a room that doesn't get any sun to preserve the colour.
