So these were in Gangjin's paper last week. I'm not really sure what's going on there, but a quick search tells me that I didn't notice when they were in the news the first time around, back in February (1, 2).
The Gangjin Shinmun article says they're called "Love Very"---why why why---and they're grown in Gundong-myeon, to the east of the county seat Gangjin-eup.
In case you're curious, yes, I did teach in Gundong-myeon once a week, at a school with 51 students. In hindsight, that was pretty neat.
