I seeded solanum pimpinellifolium along a large area where I have been putting strawberries, other perennial vegetables. They are growing pretty well now, I don't water them. The only amount of rain that we have been getting here has just been showers all in a single day, usually nothing else for a few weeks.
Suppose that counts as direct seeded / dry farmed... I will post images of the seedlings at some point this week.
