I moved from a house that had this type of grass (I guess it is grass) and would like to plant at my new house as it only requires whatever rain you get. If there is no rain it will stay brown and dry but as soon as it gets any water it will turn green. Can anyone tell me from the attached photos what this is? I live in New Mexico where we have been in a drought for ten years and are not allowed to water outside and this grass has survived. It also survives cold weather as we do have nights that are below zero in the winter. Thank You for any assistance. Tree
