Hi. I bought a plant last year at the herb festival. I haven't seen seed
for it or plants anywhere else, ever.

It grew as an annual. This year, all the plants I've seen have had no
scent! The plant I bought last year had a wonderful, really powerful scent.

So, does anybody know anything about this herb? Where to buy seeds? What
varieties are good? Does weather (it's been cold & rainy here) have an
effect on the strength of the scent?
