Thanks all (probably jazzgirl and chrise) for help with that marshland plant. I had in fact heard of that herb or spice but had no idea what it did but I would never have got it if I had not read your posts. Now am stuck on 1A as some others are and I do not play chess! I think I had better learn as my grandson asked me to play it with him and I had to say I had no idea how to.
Quite cold weather here today. Roll on spring!
