The green/orange ones are from seeds I collected from a like commercial pumpkin last year; the green stripey ones are from seeds I bought, and the butternut squashes are from seeds from last year's crop. Not a giant harvest, but plenty for everyone except mad fans of pumpkin soup. We even managed to get rid of some, I mean we served some delicious pumpkin-based recipies, to some of our gîte clients.
I have bought some commercial seeds for next year, and I will grow them (or at least plant them) in the newly-cleared area under the big walnut tree out the front. That way they won't interfere with the main veg area that is having a face-lift.
