And not always on purpose!  Last year a green bean seed somehow got among my tomato plants.  It gave me as many beans as if it had been growing on some non-living trellis, lol.   https://sarasinart.net/2013/07/17/tomatoes-and-green-beans-go-together-really/

This year as I was taking a bowl of beans to the garden to plant, I must have dropped one down in this yucca plant.  It’s spindly and I’m not sure the root is even in the ground, but it’s trying! If it starts to look really serious, I’ll give it some kind of support to grow up on.  Another of nature’s miracles; I see a lot of them in the summer.
