Lithops sp - big
Seriously giant Lithops!!
Current batch looks like LAST 2 pics. They have lots more roots now than the other pic shows. They are currently splitting, plant them right away very deep in the soil so only the tops are showing. The old leaves do have some cosmetic scarring but they will be gone soon anyway. Don't water them until the old leaves are absorbed, unless the inner leaves start to look wrinkled.
Lithops need very specific care, check out our Lithops post for more info.
