Loofahs are delish. :D

Though er, 絲瓜 is the term I use to describe the two different varieties of loofah that are eaten. They are both delish btw and taste pretty much similar.

Also, I think it's interesting that you consider the radical of 瓣 to be 瓜, as my first thought would be 辛. Then I checked the dictionary and found 瓣 under both radicals. :D
