I loved your post! Let me just add a few lines from my own experience as well. I grew up working on a local farm, from early in the morning, sometimes as early as 3 am to avoid the heat of the sun. I was always rebelling against the powers above me - my parents - that needed another hand on the farm. I promised myself I would never ever do this when I was the powers to be. Fast forward 20+ years - my main occupation is gardening. In my garden I do what I want. The wild onion story that was just described here recently - the wildly invasive plant - happened to me too. I saw the plant on a hill somewhere, that was maintained by the city. Now I think someone threw some seeds there, and I happened to see them when they were blooming. It was a small clump, tall and sturdy, with lovely cruciforms flowers. I dug a clump of 3-4 roots and brought them to my garden. Loved them. The following year - i saw them blooming, then I had to travel for work for a few weeks, and by the time I got back to the garden, they were done blooming, green capsules were all over the plants. I left them through the fall, and cut them when they were dry, late in the fall, small black seeds falling all over the small area where I planted them, and in my asparagus patch. The following year I had knee surgery late in the season, and my garden was sort of left to tend to itself. And when I came back the following spring - the wild onion plants were all over the garden - to such extent and force -that it took me 10 years after to eradicate every single one. Imagine if the seeds had some kind of umbrella, like the dandelions, and would have spread well beyond the limits of my garden. At the same time - I was warned that the hottuynia cordata plant is wildly invasive - I prepared a 2x2 feet area with aluminum sheathing around it - I could not keep it growing! I wanted to use it as a medicinal plant, nothing seemed to work. I even got the small plants from friends that grow it for food. For me nothing worked. I think some karma is at play here - but definitely knowing about the plant's behavior, and trying it in a controlled way helps.
