One lot of onions grew from a couple of old onions that had sprouted and I planted them in one of the fridge gardens. They grew and went to seed and heaps of plants grew from the seeds from them old onions.
They smell like onion and taste like onion but they are not round like onions which I find strange as the other onions were grown from seed we collected from last year and they are round and look just like like proper ones. I don't know why these ones are different and not round but I don't really care as they are a good crop and it means I can use lots and not have to buy any which is what we are aiming for. Any old sprouting onions will be planted and hopefully we will never have to buy onions again. We will let a few of these ones go to seed and see how the next crop turns out. Even if they all end up with no bottoms the tops will still be able to be used for adding flavour.
