Rather outshone by the Shark's Fin Melon, I have managed to grow three Kabocha fruit. I started with 6 seeds of which three germinated and one fell victim to damping off. So I value the fruit from the remaining two. Also these are more of a known quantity than the Shark's Fin. We have bought and cooked these before. They are very popular in the north of Japan where they are an essential element in soup curry.
I think they are rather photogenic, but I am biased!
