I have been growing tetragonia for a few years now - lush green NZ spinach that resists drought and - unless I am too tidy - self seeds everywhere. This year I got a bag of pine needles from South Brighton for my chook run and a seedling tetragonia popped up; red stemmed and far more 'weedy' than the commercial stuff but tetragonia nonetheless. I am planning to save the seeds from it just for interest - but how readily will it cross with the normal stuff? The plants are only a metre apart. A hybrid might be interesting if it keeps the red stem. Any advice?
