Yes, woofie, they were the multi-seed pellets from Harris, linked above. I love the multi seed pellets, and the extra-large flowers of clear crystal.
I'm not qualified to comment on the fragrance. My smeller is awful.
I checked my seed stash. My alyssum clear crystal are dated 2009. As of 2012, germination still excellent. So 2012 would have been my 4th year using my original 250 pellets
I haven't sown them yet this year, but I still have quite a few. I also ordered some purple, and I think it was you who recommended those.
