A thank you to Monika (half of monika&manfred@Flickr) for submitting today's photographs taken in Vienna, Austria (original image 1 and original image 2). It's worth the time to browse Monika's photographs, particularly since she has photographs from her travels around the world.
The question to ask with cucurbits is, “What aren't they used for?” If you read The Wild and Wonderful World of Gourds from Wayne Armstrong, you'll learn members of this family were or are used for: food, medicine, ornament, a sweetener, currency, an art medium, containers and eating utensils, pipes, musical instruments and clothing – not a bad list!
I believe most, if not all, of the cucurbits in today's photographs have wild origins in Mexico and South America, though if the pale one is actually a melon (Cucumis melo) instead of a squash, it would have its origin in Africa or southwest Asia. Members of the family are found throughout the tropical, subtropical and warm temperate areas of the world.
