I say "them", but I really mean "it", because I have only one plant. That said, it looks a good one.
For want of space elsewhere, I'm growing my courgette in a big (50cm diameter) tub.
Actually I think growing courgettes in tubs is an ideal way to do it, because it means that it is easier to provide the right environment for them - they like deep, rich, moisture-retentive soil. They thrive in full sunlight as long as they are kept well watered. When grown in dry soil, courgettes get stressed and succumb easily to mildew.
My plant is just producing its first fruit:
Not far behind are at least two more embryonic fruits.
I just hope that some male flowers open at the right time to permit pollination.
Sharing the big tub with the courgette plant are two cucumber plants - one "Diva" and one "Passandra". They are still small, but I have started encouraging them to climb up the bamboo canes I have provided for them.
Initially they need tying-in, but eventually they will probably be able to support themselves with the aid of their spiral tendrils.
