Hi, I planted some alpine forget-me-not seeds in a new flower bed that I made as a memorial garden. (They are for my brother). I remember reading the seed packet and it said to thin out the plants once they came up, which I tried to do. I had a few clumps. This year they seem to have overtaken the garden. Besides the bigger plants in the pictures, there are tons of new small plants covering underneath. I really did not want them to take over the garden, as I have other things planted. Is it too late? Do they spread from seeds in the flowers? Do you have any suggestions how I can keep them to a few small clumps? I am worried they are going to be like a weed I have to pull all the time. What will happen if I just leave them to do what comes naturally, I'm wondering if they will die out or just spread more? Thanks for whatever information you send. I feel silly that it doesn't seem like I planned well.
