The mystery vegetable!!

Since this is my first blog, let me introduce myself. My name is Cath and I live in Syndey NSW, Australia. I have a small vege patch in my back yard that I am absolutely loving. I discovered KGI when looking for sites with recipes to use all my garden produce. Being that we live on a small suburban block we decided that a raised vege patch would be the thing for us. So we now have a "water tank" style vege patch that sits about 80cm off the ground, is approx 2.8m long and 90cm wide. To this we also have some large ceramic pots that we grow a few things in aswell. And the strawbery pots. 2 of them so that there is more than enough strawberries for 2 strawberry lovers. When we planted out our summer seedlings this year, we noticed a small little seedling had popped up through the soil at the edge of our raised vege patch. We have been eagerly watching it and have decided its some sort of curcubit, maybe a zucchini or squash? I will post a photo of the now huge flowers and leaves and see what you all think.... as soon as I figure out how to do that. The next question we had was how did this rogue mystery vegetable get into the garden in the first place? The only answer is worm poo. We have a worm farm and about 2 weeks before planting out with seedling we had dug through the worm castings to add some good ness to the soil. This is the only place I can think of that the mystery would have come from. I have decided to make blogging about my garden a regular thing, so hopefully this is the first of many. To anyone reading thank you, have a great day and an even better time out in the garden!
