I had posted before about green beans growing climbing a tomato plant, and this year I dropped one bean in a yucca plant and it got beans on. https://sarasinart.net/2014/09/06/i-love-natures-miracles/
So, in the kitchen I have a pot of herbs. Rosemary, oregano, basil, parsley. I was standing there shelling out dried kidney beans a month or so ago, to cure them by leaving them in an open jar on the window sash for a while. I had one bean that looked deformed and not so good to eat and I just dropped it in this pot of herbs. Didn’t even cover it up, just dropped it in there.
The pot gets good eastern morning light and my herbs do well there all year round. And, it seems, so does one kidney bean plant. It shot up about a foot tall at first and I watched it to see what it would do. Then it got several flowers and now has one big and one small pod on, with beans forming. (Most beans will self pollinate.) The big one is about 1″ long. It’s already too heavy for the plant to support it so it’s getting a little help from its friend rosemary, holding it up.
It’s amazing that a seed/plant would get this far along when it is so small, but it’s thriving so far and I’m letting it do what it’s going to do. Nature is always amazing.
