How do I know if these off-shoots are truly Yucca plants?

Question

I found what I thought was a Yucca in the ditch by my driveway – I eventually threw it in a pot with some soil and water – & now I have multiple green sprouts!!!

Answer 1

Kind of hard to tell from the picture, but good for you for saving lost plants. Why don’t you just let it go ahead and grow, and as the foliage matures, you’ll be able to better tell what it is.
