Zucchini
I planted 3 zucchini because I bought a punnet. They are ridiculously large and taking up a full 1/4 of the garden.
They are overcrowded and hard to find fruit and often we end up with Marrows that in turn stunt the growth of other fruit on the plant.
Pumpkin
1 pumpkin self seeded right at the edge of the garden. I've loaded it up with cow poo and straw etc and it's already got 3 baby pumpkins on it. Yay!!
Cucumber
I planted 3 cucumber. Damn snails ate 2 of them on the first night! The last one has been slow to get going. I put a stake with it but it hasn't climbed it. I need to work out what they climb. A cucumber has self seeded and in 1/2 the time is healthier looking than the one left that I planted.
For the future:
1 green zucchini
1 yellow zucchini
2-3 cucumber with something to climb
1 pumpkin plant
