The feature on the Sea Holly is good, I have tried for 2 year now to grow it from seed with no success at all, which is a bit worrying as I am having a lot of success with everything else although I am only learning and new to all this. So I am really disappointed that It didn't grow again, any suggestions for me. I'm determined to get it to grow.
Hope you can help me
