Eye-Like Living Stone (Lithops optica)

Lithops optica

Eye-Like Living Stone (Lithops optica)

Endemic to the foggy coastal fog-belt around Lüderitz in Namibia, Lithops optica is an iconic living stone characterized by club-shaped, convex leaves with deep, translucent apical windows. While standard wild forms exhibit subtle greyish-green to opalescent tones, the renowned cultivar 'Rubra' captivates with vivid ruby-violet coloration. Distinct from most inland Lithops, it produces its white, daisy-like blossoms exceptionally late in the season, from late autumn into winter.
