African Cucumbers or Horned Melon
Have you ever tried African cucumbers? Horned melon? I have tried both. Actually it is the same fruit but with different names: wiki
It is just crazy how even cucumbers can be different. And what about people...
I have bought these cucumbers in France during Plants Festival (Fêtes de Plantes) in Castle Park of Saint-Jean-de-Beauregard (Château de Saint-Jean-de-Beauregard) - nice place for plants lovers where you can see and buy not only different plants for your garden but also almost unknown or forgotten fruit and vegetables for your table.
It is notable that being originally from Africa this melon-cucumber is now grown in California.
