I can't comment on the fragrance. My nose isn't very good.
I bought mine several years ago so I don't remember. I bought a big load of them (white) so I'm still using that same batch. I ordered some mixed colors last week from Harris. Again, it was a bunch, but they'll last me for years.

I had a free shipping offer from Harris last week, and I wanted another seed from them, so I ordered the alyssum, too.
I'm sure other companies sell them too. If you google it, I'm sure you'll find others.
