Yes, I have a bunch of them. All summer I still have to steal them from one plant to move it to support another. I have different sizes, too, and mine interlock. I bought them at Smith and Hawkin's going out of business sale. I wish I'd bought twice as many at the time. But I have so many plant stakes my husband will evict me if I buy one more- I almost need another house to store all my plant junk in winter.
