Your lithops are so beautiful! take good care of them.
Beautiful lithops Alain. I like them all but my favorite is probably the L. otzeniana, which has always been a favorite. Have you had the L. optica rubra and L. otzeniana for a long time? Beautiful clumps.
Unfortunately I do not have a record of when I got my plants but both the optica rubra and otzeniana I have had for some years.
