Pumpkins, squashes, gourds, marrows... all names for the fruit of colourful members of one plant family Cucurbitaceae.
They are grown for food but also for fun because they come in numerous varieties of colour, shape and size. Many of us will soon carve the pumpkin for fun and make the pumpkin pie for Halloween. Being so attractive, in almost every country where they are grown there are pumpkin festivals organized.
Who does not like to eat dry seed or many dishes made of these sweet fruits? I also use the oil extracted from seed in my cuisine; excellent in kidney bean salad.
These are called 'Turk Cap' (Cucurbita maxima)
Cucurbita pepo var. ovifera
Note: If you vant to get the fruit true to the type plant different varieties well away from each other. Othervise, they will cross-pollinate and there will be all kinds of fruits which is, of course, not so bad, especially if you love surprices.
