I was watching ebay the other week, and was amazed to see someone pay £6 for 'sweet orange' seeds. No variety was stated. I looked up sweet orange and found that this is the name for most of the eating oranges. Surely, they could have just bought a couple of oranges from tesco and saved the pips. I remember growing pips as a child. Would oranges grown from pips eventually bear fruit or do you need to buy special seeds ?
