I'm not a big gardener, but would like to try growing something on my apartment balcony this summer--it's worth a try, I think. I'm looking for Japanese "heirloom seeds" -- the kind of seeds that can be, and have been, preserved from less-common plants. Anyone know if and where I could find something like this in Japan?
