I have been given some Jerusalem Artichokes and I’m contemplating planting a couple. I know they can be invasive so I will probably use a large container. I cut one in half and put it in a saucer with a few drops of water to see if roots would form (which they have.) The saucer now looks as if I’ve sprinkled coarse black pepper on it (or poppy seeds.) I’ve searched the internet but can’t find anything covering the subject.
Anyone know what these are? They don’t appear to move! 🤔
