We saw plenty of evidence of crops being harvested at the weekend. Agriculture looks to be pretty labour-intensive and small scale – fields are small, surrounded by walls made of black volcanic rock. It’s often women doing the work – crouched down, large hats protecting them from the sun – reinforcing the myth (if that’s what it is) that Jeju men are lazy and the women do the work.
Some crops, like cabbages, are familiar and some less so. That’s kohlrabi (what a great name!) in the photo below; I knew the name but don’t remember having seen it growing before. Sweet potatoes (which is what the truck’s carrying) are common enough, as are normal potatoes. We also passed a field of big radish like Japanese daikon.
Notes from a Korean island 
Do you know what the vegetables in the top photo are? I see something very similar in London shops (especially Lewisham) and always wonder what they’re called
Or are these sweet potatoes and the London ones larger?
They’re sweet potatoes. Apparently, they’re only distantly related to the potatoes we’re familiar with and should not be confused with yams. They originate in South America and were introduced into Korea in 1764. (Information courtesy of Wikipedia).
We grew some kohlrabi in our garden in the UK this year – they didn’t grow all that well, but they do look very pretty, and taste ok too.
