Chinese cucumbers (Trichosanthes kirilowii) are native to China and Japan. They're dioecious, producing white "hairy" flowers from June to September and fruits from August to October. The fruits are green at first and then turn yellow. They're edible but not tasty. Someone says on the internet that he would never eat it unless famine comes😆. It's not so difficult to find Chinese cucumber flowers in Tokyo but not so when it comes to the fruits. It seems Chinese cucumbers are removed when the flower season is over.
When you see the flowers, you would likely see pumpkin beetles (Aulacophora nigripennis), too. Pumpkin beetles are harmful but their tininess, agility and color contrast between orange and black never fails to bring me a smile.
