I have a bunch of Citrus pseudogulgul (shishiyuzu, which is not generally considered a variety of yuzu) seeds awaiting germination for longer-term cultivation, but none actually growing yet. Despite most folks reporting a large number of seeds, the ones I bought this year were about half totally seedless, presumably due to intentional cultivation to avoid pollination for the gift fruit industry? I assume the approach of just importing Japanese fruit is less doable in the US than it is in Canada due to the fact that y'all have actual established citrus agriculture in the country.
