I grow wormwood, too! I got my seeds from Baker Creek. It's a beautiful plant. I love how soft its leaves are. Do be warned though...if you let it go to seed, you will probably regret it. It spreads...and FAST. I've taken to cutting the tiny yellow flowers off before they finish doing their thing. Some escape my clippers and spread their seeds, but I let those grow where they choose for the most part just to make sure if something happens to my main plants, there are still babies to fall back on. Good luck!
