ooooo now that made me excited. It's awesome when you watch them grow - apparently you can eat the flowers (I've heard stories told by my workers on the farm - they say cook it like spinach and it's yummy but I yet got to try it).
If you like zucchini / baby marrow, a single plant yields a lot so don't grow too many plants at once. My mom made that mistake and she was overwhelmed with the amount of marrows she had to pick everyday - half of her crops had to be given away to friends and struggling people at their church. In fact, she still does it with every other vegetable in the garden - helps people who are not able to buy food for their families.
