This is what they look like
Brilliant, thanks Lyn, I've just checked round the garden, two have survived weeding I now know what to look out for next year!
Have lots of seedlings this year from variety Lollipop. First year I have grown it so really pleased.
I moved one of mine last summer as it was at front of border. It survived happily, and the garden is full of seedlings, I have potted up loads and given them to friends, but now I have just started pulling them out because they are like weeds all over the place, along with Icelandic poppies. Not too worried though as we are moving soon!!!
