Flowering last Autumn.
Beautiful plants Alain. It's interesting to see the variation in color of some of the L. otzeniana selections. I really like the subtle gray of your plants. I have one that seems to have more green in the leaf color and another that has some brown in the color. One of my favorite lithops species.
I like this one. Flowers well also. I have'aquamarine' [ see 5th November 2015 ] and like the red form 'cesky granat' I am raising some SH531 which is a nice grey form. I can end up growing lots of one species again.
