Grow your own pepitas

If anyone has been reading my sourdough adventures you may have noticed that I have been adding pepitas to my loaves. They aren't all that cheap and when I went to buy some at the Health Shop the other day when they had 20% off I had a look on the back of the packet and noticed they came from China. So I wandered off to Coles to check out their pepitas for country of origin and they were the same. That got me wondering if we grew them in Australia so I asked Mr.Google and was amazed to find that you can indeed grow your own.
