Whether you're looking for a ground cover plant to suppress weeds, want to make your flower beds more attractive, or fill the empty spaces beneath trees where your lawn won't grow, there's a sedum ...
Because there are so many different species of sedum, you could easily make a garden with just these plants, combining low-growing ground cover species with taller, showier types of sedum.
take a picture of the plant or check images of succulent plants online until you can identify what type of succulent or sedum you have. Then you can look up if the variety needs winter protection.
